ryo-metadata

Status: stable. Part of the ryo workspace — AST-centric Rust programming for AI agents.

Cargo workspace and crate metadata resolution for ryo. Solves the crate:: vs actual-crate-name problem by walking cargo metadata, mapping file paths to crate names, and producing accurate SymbolPaths.

Install

cargo add ryo-metadata

Quickstart

use ryo_metadata::WorkspaceResolver;

let resolver = WorkspaceResolver::from_manifest("Cargo.toml")?;

let crate_name = resolver.crate_for_file("crates/ryo-app/src/lib.rs");
assert_eq!(crate_name, Some("ryo_app"));

for member in resolver.members() {
    println!("{}: {}", member.name, member.manifest_path);
}
