An (unofficial) sub-community of the Rust programming language that wants to close gaps you feel in Rust's ecosystem.
This README is a list with a twofold purpose:
- Enumerate specific use cases and their problems domains that do not yet have a robust ecosystem in Rust.
- The definition of "specific" and "robust" for this list is yet to be determined!
- Encourage the Rust community to approach gaps in the Rust ecosystem by providing this list as a point of collaboration!
NYAR's issue tracker can help you get ecosystem gaps filled when you participate in:
- Voting on your favorite issues to let people know you'd use something, optionally commenting and explaining your use case.
- Placing bounties on issues you're particularly passionate about, since issues are where BountySource integrates! We use the
bountytag to indicate which issues have bounties associated.

- There are many older Rust questions on Stack Overflow that wouldn't work with today's Rust because of syntax that has changed since the release of 1.0, or that may have better solutions because of other Rust ecosystem developments.
- See #4 for an SO query and a list of these known issues!
Character encodings Full support forImplemented here!
cp437(see this issue).
- Some work has been done to create OpenCV bindings in
cv-rsas well as automatically generating bindings like
opencv-rust. Neither are very complete.
- Piston has
image, but in their words, "This is very much a work in progress".
- DDS library wiki
HDF5 (see also Wikipedia and this Reddit post)A stable version of
hdf5crate has been released and is now available on crates.io.
- A good stream processing pipeline with back pressure doesn't yet exist for an asynchronous data processing pipeline
- RxRust is an older attempt to implement this according to the reactive streams model -- it currently seems closest to this use case.
futuresmay be interesting components to use when building this.
- New features soon to come in Rust like
impl Traitwill probably make developing something like this easier to develop and use.
- Bindings for pandoc
- Bindings for git-annex
std::collections::HashMap-like structure has not been fully developed yet.
concurrent-hashmapis still missing methods like
clearfrom the original
evmapis a different design around eventual consistency, and so departs from the normal
dashmapis intended to fit this use case exactly.
Dynamic programming analysis/instrumentation
- Binary instrumentation tools like Intel Pin or DynamoRIO are useful for embedded applications. An ecosystem around them (which doesn't exist yet!) could include:
- MINIX support is
nonexistent!still a WIP.
- Integration with existing mature game engines is poor at time of writing.
- Unreal Engine has had some prior work accessible by making an Unreal account, but nothing has been made freely public at time of writing.
- Unity3D currently has no published crates for Rust interop.
- Godot Engine allows Rust interop via godot-rust. Authors' note on stability:
The bindings cover most of the exposed API of Godot 3.2, and are being used on a number of projects in development, but we still expect non-trivial breaking changes in the API in the coming releases.
- No mature game engine written in pure Rust exists yet.
- Part of a mature solution will need to include a rich and robust editor. Examples can include:
- Amethyst is active and has a roadmap for becoming production-ready.
- Bevy is a new project built with the learnings of the Amethyst project. See the roadmap here.
- RG3D, a 3D game engine with an example 3D FPS game built using it.
- PCL equivalent - point clouds, essential 3D geometry functions
- Voxel library, operations and representation of voxel data. There is a piston crate for rendering voxels but this isn't suitable for working on domains like medical data, more geared towards game development. To enable processing in scientific domains like medicine there needs to be processing functions such as being able to: convert to triangular mesh, thresholding, and morphology. This is because things like MRI data is expressed as voxels, thresholding can separate grey and white matter in the brain, morphology identifies shapes and structures inside the body etc.
Geospatial Information Systems
- OGC standards - multiple crates for standards for encoding, sharing or manipulating geospatial data link. There's already a crate for GeoJSON but none of the others appear to have crates.
- More complete GDAL wrapper (or pure rust alternative). rust-gdal is an incomplete wrapper so needs work.
- Machine learning toolkit like scikit-learn in Python (both rust-learn and rusty-machine are insufficient). Rust-learn only supports classification, rusty-machines misses support for sparse data and serialization. Both of them miss quite common unsupervised techniques (like PCA).
- Deep learning toolkit with GPU support a good flexibility (think Tensorflow or Chainer in Python). Most of the current libraries are either simplistic (you cannot do seq2seq network in them for example), or miss GPU support.
- Sparse matrix libraries (SPRS library needs some love, the basics are there but advanced linear algebra is missing)
- Designing low latency DSP algorithms suitable for embedded use (common filters, analysis functions)
- Library for nonlinear dynamical or chaotic systems (solvers, numeric methods etc.)
- A pure Rust
libmimplementation. These are required to get math functions on
Native desktop application integrations
- An interactive Visual Basic uses for scripting by using the COM interface, which I believe
Networking and Protocols
- AMQP 1.0 - While there are several libraries for AMQP 0.9.1, the AMQP 1.0 spec represents a significant departure from the previous version.
Ability to parse-- implemented by this person!
Registry.polfiles from Windows machines
- Common office document formats are yet to have more mature solutions:
- There is currently no library to convert between different office document formats.
beancountdata format has no parser or emitter libraries yet.
- A builder interface for a higher-level emission API would also be nice.
- Bindings to the Python implementation of beancount do not yet exist.
- An implementation of Beancount bindings, parser, and emitter in Rust is currently WIP, and contributors have been requested.
There is no pure-Rust solution for QR decoding. The only other crate that handles QR decoding is the-- implemented by @Wanzenbug and by @piderman, the latter of which was announced on Reddit. See the PR.
quirccrate, which uses C bindings
- The RData file format does not have a parser or emitter yet.
- Currently, this formatted is implemented for the R language in the
- Currently, this formatted is implemented for the R language in the
- There are no SGML parsers or emitters on crates.io at all.
- This is mostly a legacy markup language used for legacy type setting and supported in applications like APP (AKA 3B2).
Personal information management
- Contacts via vCard have been implemented using
vobject, but no "high-level interface" exists yet that uses it or an alternative.
- iCalendar parsing has been implemented via several crates (i.e.,
vobject), but a higher-level API is missing.
- A stable Rust interpreter does not yet exist, which would made code exploration easier.
miriseems to be a step in the right direction -- it just needs some love!
- No debugging experience offers integration with
rustdoc, which would
- A rustdoc backend for generating zeal/ dash docsets is missing.
- A mature framework for Windows native UI has yet to be established.
native-windows-guiat one point claimed to be approaching feature-completion, but is now unmaintained.
- Abstractions over native UIs for each platform have yet to be available in pure Rust.
- A good reactive UI library complete with event-driven state management comparable to Redux does not yet exist.
carboxyllooks like it may be a good fundamental building block for this.
- Generation of Google bindings using
googleapisand gRPC would be more performant than using JSON web requests to the Google API, as with
- There is room for more idiomatic APIs for Google in general.
google-apis-rsuses the Google Discovery service to expose the vast majority of Google Services, but they can be difficult to grok for beginners or someone unfamiliar with Google APIs in general.
There is yet to be a library that handles all of these:
- General purpose DOM tree
- Proper encoding handling
- DTD handling
- including the disabling of features with security implications like entity expansion bombs
- XML Schema validation
- XSLT 1.0/2.0/3.0
- Option to preserve input style
- Is fast
