Struct rustc_arena::DropArena

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

An arena which can be used to allocate any type.

Safety

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<T> 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

Implementations

impl DropArena

pub unsafe fn alloc<T>(&self, object: T) -> &mut T where
    T: Send, 

pub unsafe fn alloc_from_iter<T, I>(&self, iter: I) -> &mut [T] where
    T: Send,
    I: IntoIterator<Item = T>, 

Trait Implementations

impl Default for DropArena

fn default() -> DropArena

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
