§hir_id: HirId

Implementations§

impl<'hir> GenericParam<'hir>
sourcepub fn is_impl_trait(&self) -> bool
pub fn is_impl_trait(&self) -> bool
Synthetic type-parameters are inserted after normal ones. In order for normal parameters to be able to refer to synthetic ones, scans them first.
sourcepub fn is_elided_lifetime(&self) -> bool
pub fn is_elided_lifetime(&self) -> bool
This can happen for async fn
, e.g. async fn f<'_>(&'_ self)
.
See lifetime_to_generic_param
in rustc_ast_lowering
for more information.

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.
