cargo wrapper for this library

You probably want the cargo wrapper to this library. See https://github.com/Enselic/cargo-public-items.

public_items

List public items (the public API) of a Rust library crate by analyzing the rustdoc JSON of the crate.

Usage

Again, you probably want to use the convenient cargo public-items wrapper. But if you don't want to use the cargo wrapper, you do as follows:

# Install the tool that comes with this package
cargo install public_items

# Generate rustdoc JSON for your Rust library
RUSTDOCFLAGS='-Z unstable-options --output-format json' cargo +nightly doc --lib --no-deps

# List all items in the public API of the Rust library using the tool
public_items ./target/doc/your_library.json

Example

Using the tool on its own library:

% RUSTDOCFLAGS='-Z unstable-options --output-format json' cargo +nightly doc --lib --no-deps
% public_items ./target/doc/public_items.json
pub enum public_items::Error
pub enum variant public_items::Error::SerdeJsonError
pub fn public_items::Error::fmt(self, __formatter)
pub fn public_items::Error::fmt(self, f)
pub fn public_items::Error::from(source)
pub fn public_items::Error::source(self)
pub fn public_items::sorted_public_items_from_rustdoc_json_str(rustdoc_json_str)
pub mod public_items
pub struct field 0 (path missing due to https://github.com/rust-lang/rust/issues/92945)
pub type public_items::Result

Tip: By writing the public API to a file for two different versions of your library, you can diff your public API across versions.

Target audience

Maintainers of Rust libraries that want to keep track of changes to their public API.

Limitations

Currently:

• https://github.com/rust-lang/rust/issues/92945 causes issues for enum variant tuple struct fields.
• The full type of items are not included in the output.
• Items re-exported from other crates are not included in the output.
