Struct rustc_hir_typeck::gather_locals::Declaration
source · pub(crate) struct Declaration<'a> {
pub hir_id: HirId,
pub pat: &'a Pat<'a>,
pub ty: Option<&'a Ty<'a>>,
pub span: Span,
pub init: Option<&'a Expr<'a>>,
pub origin: DeclOrigin<'a>,
}
Expand description
A declaration is an abstraction of hir::LetStmt and hir::LetExpr.
It must have a hir_id, as this is how we connect gather_locals to the check functions.

§hir_id: HirId
§pat: &'a Pat<'a>
§ty: Option<&'a Ty<'a>>
§span: Span
§init: Option<&'a Expr<'a>>

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
