Struct capnp::Word

#[repr(C)]
pub struct Word { /* private fields */ }

Eight bytes of memory with opaque interior. Use capnp_word!() to construct one of these.

This type is used to ensure that the data of a message is properly aligned.

Implementations

impl Word

pub fn allocate_zeroed_vec(length: usize) -> Vec<Word>

Does this, but faster: ::std::iter::repeat(Word(0)).take(length).collect()

pub unsafe fn bytes_to_words<'a>(bytes: &'a [u8]) -> &'a [Word]

Converts a byte slice into a Word slice. Unsafe due to possible alignment issues. Only call this if you know that either

1. bytes.to_ptr() falls on an eight-byte boundary, or
2. your processor is okay with unaligned reads.

pub unsafe fn bytes_to_words_mut<'a>(bytes: &'a mut [u8]) -> &'a mut [Word]

Converts a mutable byte slice into a mutable Word slice. Unsafe due to possible alignment issues. Only call this if you know that either

1. bytes.to_ptr() falls on an eight-byte boundary, or
2. your processor is okay with unaligned reads and writes

pub fn words_to_bytes<'a>(words: &'a [Word]) -> &'a [u8]

pub fn words_to_bytes_mut<'a>(words: &'a mut [Word]) -> &'a mut [u8]

Trait Implementations

impl Clone for Word

fn clone(&self) -> Word

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Word

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Word> for Word

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
