Function map 

Source 
pub unsafe fn map(
    allocator: &mut Allocator<'_>,
    allocation: &Allocation,
) -> Result<*mut c_void, AllocError>
Expand description

Map one allocation. Distinct regions share a reference-counted block mapping. Repeated explicit maps of the same region return AlreadyMapped.

ยงSafety

Synchronize host/GPU access. Pointers remain valid only while an explicit or persistent hold for this allocation remains live. Do not alias Rust references.
