Variants

Expr

Fields

scope: Scope

The scope for this statement; may be used as lifetime of temporaries.

expr: ExprId

The expression being evaluated in this statement.

An expression with a trailing semicolon.

Let

Fields

remainder_scope: Scope

The scope for variables bound in this let; it covers this and all the remaining statements in the block.

init_scope: Scope

The scope for the initialization itself; might be used as lifetime of temporaries.

pattern: Box<Pat<'tcx>>

let <PAT> = ...

If a type annotation is included, it is added as an ascription pattern.

initializer: Option<ExprId>

let pat: ty = <INIT>

else_block: Option<BlockId>

let pat: ty = <INIT> else { <ELSE> }

lint_level: LintLevel

The lint level for this let statement.

span: Span

Span of the let <PAT> = <INIT> part.

A let binding.
