Struct EightBytes 

pub struct EightBytes { /* private fields */ }

This is an implementation of a double-ended buffer containing byte values with storage size of 8. Single threaded usage is intended.

Implementations

impl EightBytes

Implementation of EightBytes

pub fn new() -> EightBytes

Creates a new EightBytes.

pub fn clear(&mut self)

Clears the contents of this EightBytes. The number of elements would become zero.

pub fn capacity(&self) -> u32

Returns the maximum capacity of this buffer. (always 8)

pub fn len(&self) -> u32

Returns the number of elements in this buffer.

pub fn is_empty(&self) -> bool

Returns true if this buffer is empty.

pub fn is_full(&self) -> bool

Returns true if this buffer is full.

pub fn push_back(&mut self, v: u8)

Push a value to the back of the buffer. No action performed if buffer is full.

Arguments

• v - byte value to be pushed

pub fn push_front(&mut self, v: u8)

Push a value to the front of the buffer. No action performed if buffer is full.

Arguments

• v - byte value to be pushed

pub fn pop_front(&mut self) -> Option<u8>

Removes the first element and return it. ‘None’ is returned if buffer is empty.

pub fn pop_back(&mut self) -> Option<u8>

Removes the last element and return it. ‘None’ is returned if buffer is empty.

pub fn peek_at(&self, index: usize) -> Option<u8>

Returns the byte at the ‘index’ position without removing it from the collection. The zeroth item is the oldest item from the collection.

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

Peek at the first element without removing it. ‘None’ is returned if there is nothing stored there.

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

Peek at the last element without removing it. ‘None’ is returned if there is nothing stored there.

Trait Implementations

impl Clone for EightBytes

fn clone(&self) -> EightBytes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EightBytes

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

Formats the value using the given formatter.

impl Default for EightBytes

Implementation of Default trait

fn default() -> EightBytes

Return an empty array

impl Hash for EightBytes

Hash implementation

This object is mutable; do not put EightBytes in a collection if its state will change during its residence.

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 EightBytes

Ord implementation; longer length EightBytes being greater, followed by comparison of most recently pushed bytes

This object is mutable; do not put EightBytes in a collection if its state will change during its residence.

fn cmp(&self, other: &Self) -> 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 EightBytes

PartialEq implementation

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.

impl PartialOrd for EightBytes

PartialOrd implementation

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