Expand description

A declaration is an abstraction of hir::Local and hir::Let.

It must have a hir_id, as this is how we connect gather_locals to the check functions.

Fields

hir_id: HirIdpat: &'a Pat<'a>ty: Option<&'a Ty<'a>>span: Spaninit: Option<&'a Expr<'a>>els: Option<&'a Block<'a>>

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.
