Type Alias AstId

pub type AstId<N> = InFile<FileAstId<N>>;

AstId points to an AST node in any file.

It is stable across reparses, and can be used as salsa key/value.

Aliased Type

pub struct AstId<N> {
    pub file_id: HirFileId,
    pub value: FileAstId<N>,
}

Fields

file_id: HirFileId

value: FileAstId<N>
