Struct rustc_hir::Local[−][src]

pub struct Local<'hir> {
    pub pat: &'hir Pat<'hir>,
    pub ty: Option<&'hir Ty<'hir>>,
    pub init: Option<&'hir Expr<'hir>>,
    pub hir_id: HirId,
    pub span: Span,
    pub source: LocalSource,
}
Expand description

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

Fields

pat: &'hir Pat<'hir>ty: Option<&'hir Ty<'hir>>
Expand description

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

init: Option<&'hir Expr<'hir>>
Expand description

Initializer expression to set the value, if any.

hir_id: HirIdspan: Spansource: LocalSource
Expand description

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