Struct TypedArena 

pub struct TypedArena<'arena, T> {
    _lives: PhantomData<&'arena T>,
    _drops: PhantomData<T>,
    chunks: RefCell<Vec<ArenaChunk<T>>>,
    head: Cell<*mut T>,
    tail: Cell<*mut T>,
}

A TypedArena can hold many instances of a single type, and will properly Drop them when it falls out of scope.

Fields

_lives: PhantomData<&'arena T>

_drops: PhantomData<T>

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

head: Cell<*mut T>

tail: Cell<*mut T>
