pub(crate) fn iter_self_type_or_consts( &self, ) -> impl Iterator<Item = (TypeOrConstParamId, &'db TypeOrConstParamData)>

pub(crate) fn iter( &self, consider_late_bound: bool, ) -> impl Iterator<Item = (GenericParamId, GenericParamDataRef<'db>)>

Iterate over the parent params followed by self params.

pub(crate) fn iter_id( &self, consider_late_bound: bool, ) -> impl Iterator<Item = GenericParamId>

pub(crate) fn len(&self, consider_late_bound: bool) -> usize

Returns total number of generic parameters in scope, including those from parent.

pub(crate) fn len_parent(&self) -> usize

pub(crate) fn len_lifetimes_self(&self) -> usize

pub(crate) fn provenance_split(&self) -> ProvenanceSplit

fn find_owner(&self, def: GenericDefId) -> &SingleGenerics<'db>

pub(crate) fn type_or_const_param_idx(&self, param: TypeOrConstParamId) -> u32

pub(crate) fn lifetime_param_idx( &self, param: LifetimeParamId, is_lowering_impl_trait_bounds: bool, ) -> (u32, bool)

pub(crate) fn empty(def: GenericDefId) -> Self

👎Deprecated:

don’t use this; it’s easy to expose an erroneous Generics with this

fn opaque_lifetime_idx(&self, param: LifetimeParamId) -> usize
