We can set this to true because the disabled allocator returns dangling pointers which are valid in a system allocation.

type Alloc<T> = EmptyBuf<T>

A raw allocation from the allocator.

fn alloc<T>(self, _: T) -> Result<Self::Alloc<T>, AllocError>

Construct an empty uninitialized raw allocation with an alignment matching that of T that is associated with this allocator.

fn alloc_empty<T>(self) -> Self::Alloc<T>

Construct an empty uninitialized raw vector with an alignment matching that of T that is associated with this allocator.

fn clone(&self) -> Disabled

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Disabled
