Source§fn visit_vars(&mut self, v: &mut impl VarsVisitor)
fn visit_vars(&mut self, v: &mut impl VarsVisitor)
Visit the variables contained in
self, as seen from the outside of self. This means
that any variable bound inside self will be skipped, and all the seen De Bruijn indices
will count from the outside of self.Source§fn substitute(self, generics: &GenericArgs) -> Self
fn substitute(self, generics: &GenericArgs) -> Self
Substitute the generic variables inside
self by replacing them with the provided values.
Note: if self is an item that comes from a TraitDecl, you must use
substitute_with_self or substitute_inner_binder, otherwise you’ll get panics.Source§fn substitute_inner_binder(self, generics: &GenericArgs) -> Self
fn substitute_inner_binder(self, generics: &GenericArgs) -> Self
Substitute the generic variables inside
self by replacing them with the provided values.
This is appropriate when substituting an inner binder.Source§fn substitute_explicits(self, generics: &GenericArgs) -> Self
fn substitute_explicits(self, generics: &GenericArgs) -> Self
Substitute only the type, region and const generic args.

self,
generics: &GenericArgs,

fn substitute_with_self( self, generics: &GenericArgs, self_ref: &TraitRefKind, ) -> Self
Substitute the generic variables as well as the
TraitRefKind::SelfId trait ref.Source§fn substitute_with_tref(self, tref: &TraitRef) -> Self

Source§fn move_under_binder(self) -> Self
fn move_under_binder(self) -> Self
Move under one binder.
Source§fn move_under_binders(self, depth: DeBruijnId) -> Self
fn move_under_binders(self, depth: DeBruijnId) -> Self
Move under
depth binders.Source§fn move_from_under_binder(self) -> Option<Self>
fn move_from_under_binder(self) -> Option<Self>
Move from under one binder.
Source§fn move_from_under_binders(self, depth: DeBruijnId) -> Option<Self>
fn move_from_under_binders(self, depth: DeBruijnId) -> Option<Self>
Move the value out of
depth binders. Returns None if it contains a variable bound in
one of these depth binders.Source§fn visit_db_id<B>(
&mut self,
f: impl FnMut(&mut DeBruijnId) -> ControlFlow<B>,
) -> ControlFlow<B>
fn visit_db_id<B>( &mut self, f: impl FnMut(&mut DeBruijnId) -> ControlFlow<B>, ) -> ControlFlow<B>
Visit the de Bruijn ids contained in
self, as seen from the outside of self. This means
that any variable bound inside self will be skipped, and all the seen indices will count
from the outside of self.Source§fn replace_erased_regions(self, f: impl FnMut() -> Region) -> Self
fn replace_erased_regions(self, f: impl FnMut() -> Region) -> Self
Replace all the erased regions by the output of the provided function. Binders levels are
handled automatically.
