Fields§

§scopes: Vec<Scope>§breakable_scopes: Vec<BreakableScope<'tcx>>

The current set of breakable scopes. See module comment for more details.

§if_then_scope: Option<IfThenScope>

The scope of the innermost if-then currently being lowered.

§unwind_drops: DropTree

Drops that need to be done on unwind paths. See the comment on DropTree for more details.

§generator_drops: DropTree

Drops that need to be done on paths to the GeneratorDrop terminator.
