Required Associated Types

type Id: Copy

Required Methods

fn parsers() -> &'static LazyLock<GroupTypeInner<Self>>

fn emit_err<'sess>( &self, sess: &'sess Session, diag: impl for<'x> Diagnostic<'x>, ) -> ErrorGuaranteed

fn should_emit(&self) -> ShouldEmit

fn id_is_crate_root(id: Self::Id) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl Stage for Early

type Id = NodeId

impl Stage for Late

type Id = HirId
