Struct Buffer

pub struct Buffer(/* private fields */);

A buffer of bytes.

Implementations

impl Buffer

pub fn new() -> Self

Create a new general purpose byte buffer.

pub fn extend_from_slice(&mut self, slice: &[u8])

Extend the given buffer with the contents of another slice.

pub fn len(&self) -> usize

Get the current length of the buffer.

pub fn is_empty(&self) -> bool

Check whether the buffer is empty.

Trait Implementations

impl AsMut<[u8]> for Buffer

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[u8]> for Buffer

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for Buffer

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

Formats the value using the given formatter.

impl Default for Buffer

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a [u8]> for Buffer

fn from(slice: &'a [u8]) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Buffer

fn from(vec: Vec<u8>) -> Self

Converts to this type from the input type.

impl<'lifetime> FromBytesWithInput<'lifetime> for Buffer

type Input = usize

The type of the additional input.

fn from_bytes_with_input( buffer: &mut Cursor<&'lifetime [u8]>, input: Self::Input, ) -> Result<Self, DeError>

Takes a byte buffer and an additional input and returns the deserialized data structure.

impl PartialEq for Buffer

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Size for Buffer

fn unpadded_size(&self) -> usize

Size of the unpadded data structure. This will usually only be unaligned for variable length types like strings or byte buffers.

fn padded_size(&self) -> usize

Get the size of of the payload and align it to the required netlink byte alignment.

impl ToBytes for Buffer

fn to_bytes(&self, buffer: &mut Cursor<Vec<u8>>) -> Result<(), SerError>

Takes a byte buffer and serializes the data structure into it.

fn pad(&self, buffer: &mut Cursor<Vec<u8>>) -> Result<(), SerError>

Pad a netlink message to the appropriate alignment.
