Expand description

Hints at the original code for a let statement.

Variants

Normal

A match _ { .. }.

ForLoopDesugar

A desugared for _ in _ { .. } loop.

AsyncFn

When lowering async functions, we create locals within the async move so that all parameters are dropped after the future is polled.

async fn foo(<pattern> @ x: Type) {
    async move {
        let <pattern> = x;
    }
}
AwaitDesugar

A desugared <expr>.await.

AssignDesugar(Span)

A desugared expr = expr, where the LHS is a tuple, struct or array. The span is that of the = sign.

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.
