Struct rustc_hir::hir::Local

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

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.

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.
