Struct rustc_hir_typeck::gather_locals::Declaration

pub(crate) struct Declaration<'a> {
    pub hir_id: HirId,
    pub pat: &'a Pat<'a>,
    pub ty: Option<&'a Ty<'a>>,
    pub span: Span,
    pub init: Option<&'a Expr<'a>>,
    pub els: Option<&'a Block<'a>>,
}

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: HirId

pat: &'a Pat<'a>

ty: Option<&'a Ty<'a>>

span: Span

init: Option<&'a Expr<'a>>

els: Option<&'a Block<'a>>

Trait Implementations

impl<'a> From<&'a Let<'a>> for Declaration<'a>

fn from(let_expr: &'a Let<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Local<'a>> for Declaration<'a>

fn from(local: &'a Local<'a>) -> Self

Converts to this type from the input type.

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.
