impl Clone for Bytes4

fn clone(&self) -> Bytes4

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Bytes4

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

Formats the value using the given formatter.

impl Default for Bytes4

fn default() -> Bytes4

Returns the “default value” for a type.

impl Deref for Bytes4

type Target = [u8; 4]

The resulting type after dereferencing.

impl Deserialize for Bytes4

fn decode_static<I: Input + ?Sized>(buffer: &mut I) -> Result<Self, Error>

Decodes static part of Self from the buffer.

fn decode_dynamic<I: Input + ?Sized>( &mut self, buffer: &mut I, ) -> Result<(), Error>

Decodes dynamic part of the information from the buffer to fill Self. The default implementation does nothing. Dynamically-sized contains should override this.

fn from_bytes(buffer: &[u8]) -> Result<Self, Error>

Helper method for deserializing Self from bytes.

impl Display for Bytes4

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

Formats the value using the given formatter.

impl From<[u8; 4]> for Bytes4

fn from(bytes: [u8; 4]) -> Self

Converts to this type from the input type.

impl From<Bytes4> for [u8; 4]

fn from(salt: Bytes4) -> [u8; 4]

impl LowerHex for Bytes4

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

Formats the value using the given formatter.

impl Ord for Bytes4

fn cmp(&self, other: &Bytes4) -> 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,

impl PartialEq for Bytes4

fn eq(&self, other: &Bytes4) -> 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.

fn partial_cmp(&self, other: &Bytes4) -> 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.
