Project structure

In this project is 9 different crates, one in each subfolder. In general, they all have a layout like:

Cargo.toml
src/
|   (lib|main).rs

Explanation of the different crates

• prelude: a small set of shared APIs throughout most of the crates
• object_capabilities: the implementation of a small API for I/O operations with object capabilities
• object_diecup: a small crate using the API defined in object_capabilities
• object_entrypoint: a small program using the object_diecup with a custom authenticator for the IO capability
• token_capabilities: the implementation of a small API for I/O operations with tokens as capabilities
• token_diecup: a small crate taking a closure for doing I/O
• token_entrypoint is a small program implementing a simple closure using token_capabilities to use the token_diecup crate
• facet_external is a small example of a crate exposing an API taking a closure
• facet_entrypoint is a small program using a closure to implement the facet pattern

The main purpose of the Cargo.toml files is to specify dependencies. The source code is in the .rs files. All entry points are called {something}_entrypoint and have a main.rs file in their source.

Running the code

If a working rust toolchain is installed, these Crates can be run, in their respective directories running cargo run. This builds a debug build of the crate and all of its dependencies and runs it.

If a rust toolchain is not present, the recommended way of getting it is by going to (rustup.rs)[https://rustup.rs], and following the instructions.
