Struct Mmap 

#[non_exhaustive]
pub struct Mmap {}

Available on crate feature full only.

A basic map of virtual to physical memory.

In certain build configurations, this may include guard pages to check for out-of-bounds access. If a guaranteed amount of virtual address space usage of virtual location is required, see UncheckedMmap.

When combined with virtual_location, the use of guard pages may mean that the valid start of the virtual allocation is not at the requested location. Retrieve the valid start using virtual_valid_start, as_ptr, or similar after creating the mapping to get the correct address.
