Struct region::Allocation

pub struct Allocation { /* private fields */ }

A handle to an owned region of memory.

This handle does not dereference to a slice, since the underlying memory may have been created with Protection::NONE.

Implementations

impl Allocation

pub fn as_ptr<T>(&self) -> *const T

Returns a pointer to the allocation’s base address.

The address is always aligned to the operating system’s page size.

pub fn as_mut_ptr<T>(&mut self) -> *mut T

Returns a mutable pointer to the allocation’s base address.

pub fn as_ptr_range<T>(&self) -> Range<*const T>

Returns two raw pointers spanning the allocation’s address space.

The returned range is half-open, which means that the end pointer points one past the last element of the allocation. This way, an empty allocation is represented by two equal pointers, and the difference between the two pointers represents the size of the allocation.

pub fn as_mut_ptr_range<T>(&mut self) -> Range<*mut T>

Returns two mutable raw pointers spanning the allocation’s address space.

pub fn as_range(&self) -> Range<usize>

Returns a range spanning the allocation’s address space.

pub fn len(&self) -> usize

Returns the size of the allocation in bytes.

The size is always aligned to a multiple of the operating system’s page size.

Trait Implementations

impl Drop for Allocation

fn drop(&mut self)
