Function proc_macro_crate::crate_name

pub fn crate_name(orig_name: &'static str) -> Result<String, String>

Find the crate name for the given orig_name in the current Cargo.toml.

orig_name should be the original name of the searched crate.

The current Cargo.toml is determined by taking CARGO_MANIFEST_DIR/Cargo.toml.

Returns

• Ok(orig_name) if the crate was found, but not renamed in the Cargo.toml.
• Ok(RENAMED) if the crate was found, but is renamed in the Cargo.toml. RENAMED will be the renamed name.
• Err if an error occurred.

The returned crate name is sanitized in such a way that it is a valid rust identifier. Thus, it is ready to be used in extern crate as identifier.
