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

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

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).

Retry(U, String)

Expansion could not produce a result and needs to be retried. The string is an explanation that will be printed if we are stuck in an infinite retry loop.
