Implementations

impl Format

pub const fn as_byte(&self) -> u8

Return the marker byte for this format.

pub const fn from_byte(byte: u8) -> Self

Parse a marker byte into a Format value.

pub const fn as_slice(&self) -> [u8; 1]

Return the marker byte wrapped in a single‑byte array.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Format

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

Formats the value using the given formatter.

impl<'de> DecodeBorrowed<'de> for Format

type Value = Format

The decoded value.

fn decode_borrowed<R>(reader: &mut R) -> Result<Self::Value, Error<R::Error>>

where R: IoRead<'de>,

Decode the next value.

fn decode_borrowed_with_format<R>( format: Format, _reader: &mut R, ) -> Result<Self::Value, Error<R::Error>>

where R: IoRead<'de>,

Decode with a previously read Format.

impl<W> Encode<W> for Format

where W: IoWrite,

fn encode(&self, writer: &mut W) -> Result<usize, Error<<W as IoWrite>::Error>>

Encode this value to MessagePack and write bytes to writer.

impl IntoIterator for Format

type Item = u8

The type of the elements being iterated over.

type IntoIter = IntoIter<u8, 1>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Ord for Format

fn cmp(&self, other: &Format) -> 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 Format

fn eq(&self, other: &Format) -> 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 Format

fn partial_cmp(&self, other: &Format) -> 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.
