Expand description

Represents a let statement (i.e., let <pat>:<ty> = <init>;).

Fields§

§pat: &'hir Pat<'hir>§ty: Option<&'hir Ty<'hir>>

Type annotation, if any (otherwise the type will be inferred).

§init: Option<&'hir Expr<'hir>>

Initializer expression to set the value, if any.

§els: Option<&'hir Block<'hir>>

Else block for a let...else binding.

§hir_id: HirId§span: Span§source: LocalSource

Can be ForLoopDesugar if the let statement is part of a for loop desugaring. Otherwise will be Normal.
