Fields

free_all: void,

Releases all allocated memory in the arena.

retain_capacity: void,

This will pre-heat the arena for future allocations by allocating a large enough buffer for all previously done allocations. Preheating will speed up the allocation process by invoking the backing allocator less often than before. If reset() is used in a loop, this means that after the biggest operation, no memory allocations are performed anymore.

retain_with_limit: usize,

This is the same as retain_capacity, but the memory will be shrunk to this value if it exceeds the limit.
