Implementations

impl<'hir> GenericParam<'hir>

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.

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.
