Fields

captured: UnorderedHashMap<MemberPath, VariableId>

Maps captured member paths to a clusure that captured them.

closures: UnorderedHashMap<VariableId, ClosureInfo>

Maps the variable id of a closure to the closure info.

Implementations

impl SemanticLoweringMapping

pub fn topmost_mapped_containing_member_path( &mut self, member_path: MemberPath, ) -> Option<MemberPath>

Returns the topmost mapped member path containing the given member path, or None no such member path exists in the mapping.

pub fn get_scattered_members( &mut self, member_path: &MemberPath, ) -> Option<Vec<MemberPath>>

Returns the scattered members of the given member path, or None if the member path is not scattered.
