Struct rustc_mir::borrow_check::region_infer::values::PlaceholderIndices[][src]

pub(crate) struct PlaceholderIndices {
    indices: FxIndexSet<PlaceholderRegion>,
}

Maps from ty::PlaceholderRegion values that are used in the rest of rustc to the internal PlaceholderIndex values that are used in NLL.

Fields

indices: FxIndexSet<PlaceholderRegion>
