Openstreep Map Data In Rust

A crate for working with openstreetmap data.

Currently supports loading from both XML and protobuf.

API

The main class is osm::File which contains the information loaded from a source file. This class has two constructors depending on the format of your data:

osm::File::from_reader(r: impl Read)  // for osm-xml data

osm::File::from_proto_reader(r: impl Read)  // for protobuf encoded data

You can check src/main.rs for example on how to parse data. When running cargo build a binary file is created that takes a local file path to an either OSM-XML or protobuf encoded data file. Depending on the file extension the binary will use the appropriate constructor.

TODO

This crate is mostly a learning experience with rust so I do not take this too seriously.

Multi-threaded Reading of Protobuf Files

The loading of protobuf encoded files is quite fast as it is, loading all data in Sweden takes about 15 seconds, but I would like to try and make it event faster using multi-threading.

Here is an example of where i do this iterating over a osm::proto::FileBlockIterator. That code is however a bit long and messy maybe. Will just need to clean it up a little.

Better Docs

Need to read up on how you are supposed to write good docs for rust crates.
