Trait ra_ap_hir::HasSource

type Ast

Required Methods

fn source(self, db: &dyn HirDatabase) -> Option<InFile<Self::Ast>>

Fetches the definition’s source node. Using [crate::Semantics::source] is preferred when working with crate::Semantics, as that caches the parsed file in the semantics’ cache.

The current some implementations can return InFile instead of Option<InFile>. But we made this method Option to support rlib in the future by https://github.com/rust-lang/rust-analyzer/issues/6913
