Variants

Expr

An expression with a trailing semicolon.

Fields of Expr

scope: Scope

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

expr: ExprId

The expression being evaluated in this statement.

Let

init_scope: Scope

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

pattern: Pat<'tcx>

let <PAT> = ...

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

initializer: Option<ExprId>

let pat: ty = <INIT>

lint_level: LintLevel

The lint level for this let statement.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
