Trait xalloc::arena::UnsafeArenaWithMembershipCheck

pub trait UnsafeArenaWithMembershipCheck<T>: UnsafeArena<T> {
    unsafe fn contains_unchecked(&self, ptr: &Self::Ptr) -> bool;
}

Homogeneous memory arena types capable of checking whether a given pointer was created by the same instance of the arena.

Required Methods

unsafe fn contains_unchecked(&self, ptr: &Self::Ptr) -> bool

Return true if the pointer was created from the same instance of the arena.

Calling this with an already-freed pointer or an uninitialized pointer might result in an undefined behavior.
