}

Fields

index: usize

params: &'hir [GenericParam<'hir>]

Implementations

impl<'hir> DelegationGenericArgsIterator<'hir>

During generic args propagation we need to create generic args (and their HirIds) on demand, as some of generic args can not be used and in this case an assert of an unseen HirId will be triggered. Moreover, when replacing infers with generated generic params we should reuse existing HirId of replaced infer, thus this iterator abstracts the way HirIds are created for new generic args.

pub(super) fn next( &mut self, ctx: &mut LoweringContext<'_, 'hir>, hir_id_factory: impl FnOnce(&mut LoweringContext<'_, 'hir>) -> HirId, ) -> Option<GenericArg<'hir>>

pub(super) fn consume_all( self, ctx: &mut LoweringContext<'_, 'hir>, ) -> Vec<GenericArg<'hir>>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
