Struct swim_mem::block::Block

pub struct Block<'a> { /* fields omitted */ }

Address, size, and lifetime of a raw memory area.

Methods

impl<'a> Block<'a>

pub const fn empty() -> Block<'a>

Returns a zero-length Block with an undereferenceable sentinel pointer.

pub const unsafe fn from_raw_parts(data: *mut u8, size: usize) -> Block<'a>

Constructs a Block from a non-zero data pointer to size bytes.

Safety

The returned Block logically takes ownership of the pointed-to data.

pub fn from_slice(slice: &'a mut [u8]) -> Block<'a>

Constructs a Block from a slice of bytes.

Safety

The returned Block logically takes ownership of the bytes in slice.

pub fn size(&self) -> usize

Returns the number of bytes of memory owned by this Block.

pub fn as_slice(&self) -> &[u8]

Returns a slice of the memory owned by this Block.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Returns a mutable slice of the memory owned by this Block.

pub fn as_ptr(&self) -> *mut u8

Returns a pointer to the memory owned by this Block.

pub fn into_raw(self) -> *mut u8

Consumes this Block and returns a mutable pointer to its memory.

Trait Implementations

impl<'a> PartialEq<Block<'a>> for Block<'a>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.
