[][src]Struct rustc_arena::DropArena

pub struct DropArena {
    destructors: RefCell<Vec<DropType>>,
    arena: DroplessArena,
}

An arena which can be used to allocate any type. Allocating in this arena is unsafe since the type system doesn't know which types it contains. In order to allocate safely, you must store a PhantomData alongside this arena for each type T you allocate.

Fields

destructors: RefCell<Vec<DropType>>

A list of destructors to run when the arena drops. Ordered so destructors gets dropped before the arena since its destructor can reference memory in the arena.

arena: DroplessArena
