Implementations

impl NestedBindingsDefinitionKind

pub fn visible_binding_sources<'index, 'db>( &'index self, index: &'index SemanticIndex<'db>, scope: FileScopeId, ) -> impl Iterator<Item = BindingWithConstraintsIterator<'index, 'db>> + 'index

Returns nested binding sources that can update the same variable as scope.

A synthetic binding can collect both global and nonlocal writes to one name:

x = 0

def outer():
    x = 1

    def change_global():
        global x
        x = 2

    def change_nonlocal():
        nonlocal x
        x = 3

Only change_nonlocal can update outer’s local x. Nested functions also cannot capture a class-local variable, so class scopes do not see nonlocal writes to their own bindings.
