The Rust documentation problem

Rust projects have rustdoc and docs.rs, but building a compelling README with usage examples, feature flags explained, and architecture context still takes hours of manual writing that most developers skip.

Frequently asked questions about Rust documentation

Does it handle Rust workspaces with multiple crates?

Yes. Codec8 reads the workspace Cargo.toml and generates documentation for each member crate, plus an overview showing how they relate and which crate to depend on for what.

Can it document unsafe code sections?

Yes. Codec8 flags and documents unsafe blocks with special attention, explaining the safety invariants expected by the caller when such context is available in comments.

What async runtimes does it support documenting?

Codec8 detects tokio, async-std, and smol from your Cargo.toml and generates async usage examples appropriate for the runtime your crate targets.
