## Implementations§

source§

### impl<'hir> GenericParam<'hir>

source

#### 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.

source

#### 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.

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.
