Enum rustc_expand::base::ExpandResult[−][src]

pub enum ExpandResult<T, U> {
    Ready(T),
    Retry(U),
}

Expand description

Result of an expansion that may need to be retried. Consider using this for non-MultiItemModifier expanders as well.

Variants

Ready(T)

Expansion produced a result (possibly dummy).

Tuple Fields of Ready

0: T

Retry(U)

Expansion could not produce a result and needs to be retried.

Tuple Fields of Retry

0: U

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
