This crate defines the #[derive(Entry)] macro. You should be using the
metrique-writer crate, rather than referring to this crate directly.
The difference between the Entry and the MetriqueEntry macros,
is that the Entry macro generates paths that depend on metrique-writer,
and the MetriqueEntry macro generates paths that depend on metrique. The
corresponding crates re-export the right macro to ensure you only need
to have a single dependency in your Cargo.toml.
