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: HirIdspan: Spansource: LocalSource

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