Expand description

An arena that can hold objects of only one type.

Fields

ptr: Cell<*mut T>

A pointer to the next object to be allocated.

end: Cell<*mut T>

A pointer to the end of the allocated area. When this pointer is reached, a new chunk is allocated.

chunks: RefCell<Vec<ArenaChunk<T>>>

A vector of arena chunks.

_own: PhantomData<T>

Marker indicating that dropping the arena causes its owned instances of T to be dropped.

Implementations

Allocates an object in the TypedArena, returning a reference to it.

Ensures there’s enough space in the current chunk to fit len objects.

Grows the arena.

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.
