}Expand description
General trait for working with any memory-safe representation of a contiguous region of arbitrary mutable memory.
Required methods
fn as_mut_ptr(&mut self) -> *mut u8
fn as_mut_ptr(&mut self) -> *mut u8
Get a mutable pointer to the start of the allocated region.
Provided methods
fn write_volatile<T: Scalar>(&mut self, offset: usize, value: T)
fn write_volatile<T: Scalar>(&mut self, offset: usize, value: T)
Performs a volatile write of the value at a given offset.
Volatile operations are intended to act on I/O memory, and are guaranteed to not be elided or reordered by the compiler across other volatile operations.
fn write_unaligned<T: Scalar>(&mut self, offset: usize, value: T)
fn write_unaligned<T: Scalar>(&mut self, offset: usize, value: T)
Performs an unaligned write of the value at a given offset.
