Struct xalloc::arena::checked::CheckedArena

pub struct CheckedArena<T> { /* private fields */ }

Naïve memory-safe implementation of Arena.

For a test purpose only. Do not use this in production. It is really slow.

Implementations

impl<T> CheckedArena<T>

pub fn new() -> Self

Construct a CheckedArena.
