Enum Bytes

pub enum Bytes {
    Empty,
    Byte(u8),
    Word([u8; 4]),
    Bytes(Vec<u8>),
}

A blob of bytes; optimized over byte and word.

Variants

Empty

Byte(u8)

Word([u8; 4])

Bytes(Vec<u8>)

Implementations

impl Bytes

pub fn from_bytes(bytes: Vec<u8>) -> Self

Construct a blob from raw bytes.

pub fn from_slice(b: &[u8]) -> Self

Construct a blob from a slice of bytes. Clones them.

pub fn len(&self) -> usize

Get the length of this blob of bytes.

pub fn is_empty(&self) -> bool

Return true if self is empty.

pub fn is_byte(&self) -> bool

Return true if there is exactly 1 byte.

pub fn pop(&mut self, size: usize) -> Self

Pop some bytes from head. This requires allocation.

pub fn bytes(self) -> Vec<u8>

Take ownership of all bytes.

pub fn byte(&self) -> Option<u8>

Get exactly a byte; otherwise None

pub fn word(&self) -> Option<[u8; 4]>

Get exactly a word; otherwise None

pub fn append(&mut self, other: Self)

Append some bytes. This may require re-allocation.

pub fn take(&mut self) -> Self

Take ownership of all bytes; leaving self Empty.

impl Bytes

IO methods

pub async fn read_from( file: &mut impl ByteSource, size: usize, ) -> Result<Self, FileErr>

pub fn write_to(self, sink: &mut impl ByteSink) -> Result<usize, FileErr>

Trait Implementations

impl Appendable for Bytes

fn append(&mut self, bytes: Bytes)

impl Clone for Bytes

fn clone(&self) -> Bytes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bytes

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

Formats the value using the given formatter.

impl Default for Bytes

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Bytes

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