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.
