Enum StableBuf 

pub enum StableBuf {
    Vec(Vec<u8>),
    BytesMut(BytesMut),
}

A buffer whose memory is stable as long as its not reallocated.

Variants

Vec(Vec<u8>)

BytesMut(BytesMut)

Implementations

impl StableBuf

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

Returns a raw pointer to this buffer.

pub fn len(&self) -> usize

Returns the length of the buffer.

pub fn is_empty(&self) -> bool

Returns whether this buffer is empty.

pub fn put_slice(&mut self, src: &[u8])

Copies the given byte slice into this buffer. src must not overlap with this buffer. Panics if src exceeds this buffer’s length.

pub fn truncate(&mut self, len: usize)

Truncates the buffer to the specified length.

Trait Implementations

impl AsMut<[u8]> for StableBuf

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

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

impl AsRef<[u8]> for StableBuf

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

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

impl Clone for StableBuf

fn clone(&self) -> StableBuf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StableBuf

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

Formats the value using the given formatter.

impl Default for StableBuf

fn default() -> Self

Returns the “default value” for a type.

impl From<BytesMut> for StableBuf

fn from(b: BytesMut) -> Self

Converts to this type from the input type.

impl From<StableBuf> for Bytes

fn from(buf: StableBuf) -> Self

Converts to this type from the input type.

impl From<StableBuf> for Vec<u8>

fn from(buf: StableBuf) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for StableBuf

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

Converts to this type from the input type.

impl Index<usize> for StableBuf

type Output = u8

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for StableBuf

fn eq(&self, other: &StableBuf) -> 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.
