Struct copy_arena::Arena

pub struct Arena { /* fields omitted */ }

Holds the backing memory for allocated objects out of itself.

Actual allocation into the Arena happens via an Allocator returned from allocator().

Methods

impl Arena

fn new() -> Arena

Construct a new Arena. This does allocate an block of memory.

fn with_capacity(capacity: usize) -> Arena

Construct a new Arena with the given initial capacity.

The chosen capacity does not limit the final size of the arena.

fn allocator(&mut self) -> Allocator

Construct an Allocator for this arena.

fn capacity(&self) -> usize

Get the number of bytes of memory that have been allocated in service of this arena. Not all of this capacity is necessarily useful, since asked-for memory may not perfectly fit in the underlying blocks allocated.

Trait Implementations

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
