impl<T, L, C> GenericParamExt for GenericParam<T, L, C>

type TypeParam = T

type LifetimeDef = L

type ConstParam = C

fn as_type_param(&self) -> Option<&T>

If this GenericParam is a type param, get the underlying value.

fn as_lifetime_def(&self) -> Option<&L>

If this GenericParam is a lifetime, get the underlying value.

fn as_const_param(&self) -> Option<&C>
