List public items (the public API) of a Rust library crate by analyzing the rustdoc JSON of the crate.
Automatically builds the rustdoc JSON for you, which requires a nightly Rust toolchain to be installed (see here).
cargo install cargo-public-items
To print all items that make up the public API of your Rust library crate, simply do this:
cd your-rust-library
cargo public-items
and the public API will be printed with one line per item:
pub mod your_rust_library
pub fn your_rust_library::some_function()
pub struct your_rust_library::SomeStruct
pub struct field your_rust_library::SomeStruct::some_struct_member
pub struct field your_rust_library::SomeStruct::another_struct_member
Tip: If you pipe the output of different versions of your library to different files, you can use diff to diff the public API of your Rust library across versions.
Maintainers of Rust libraries that want to keep track of changes to their public API.
This utility is a convenient cargo wrapper around the publicitems crate (https://github.com/Enselic/publicitems).
