Struct ByteBuf

pub struct ByteBuf { /* private fields */ }

A wrapper around Vec<u8> to serialize more efficiently.

This has a specialized implementation of RmpWrite It gives std::convert::Infailable for errors. This is because writing to Vec<T> can only fail due to allocation.

This has the additional benefit of working on #[no_std]

Implementations

impl ByteBuf

pub fn new() -> Self

Construct a new empty buffer

pub fn with_capacity(capacity: usize) -> Self

Construct a new buffer with the specified capacity

See Vec::with_capacity for details

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

Unwrap the underlying buffer of this vector

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

Wrap the specified vector as a ByteBuf

pub fn as_vec(&self) -> &Vec<u8>

Get a reference to this type as a Vec

pub fn as_mut_vec(&mut self) -> &mut Vec<u8>

Get a mutable reference to this type as a Vec

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

Get a reference to this type as a slice of bytes (&[u8])

Trait Implementations

impl AsMut<Vec<u8>> for ByteBuf

fn as_mut(&mut self) -> &mut Vec<u8>

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

impl AsRef<[u8]> for ByteBuf

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

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

impl AsRef<Vec<u8>> for ByteBuf

fn as_ref(&self) -> &Vec<u8>

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

impl Clone for ByteBuf

fn clone(&self) -> ByteBuf

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ByteBuf

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

Formats the value using the given formatter.

impl Default for ByteBuf

fn default() -> ByteBuf

Returns the “default value” for a type.

impl From<ByteBuf> for Vec<u8>

fn from(buf: ByteBuf) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for ByteBuf

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

Converts to this type from the input type.

impl Hash for ByteBuf

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ByteBuf

fn cmp(&self, other: &ByteBuf) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ByteBuf

fn eq(&self, other: &ByteBuf) -> 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 PartialOrd for ByteBuf

fn partial_cmp(&self, other: &ByteBuf) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RmpWrite for ByteBuf

type Error = Infallible

fn write_u8(&mut self, val: u8) -> Result<(), Self::Error>

Write a single byte to this stream

fn write_bytes(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write a slice of bytes to the underlying stream

impl Eq for ByteBuf
