Struct e_write_buffer::WriteBuffer

pub struct WriteBuffer<const N: usize> { /* fields omitted */ }

A write buffer

Implementations

impl<const N: usize> WriteBuffer<N>

pub fn new() -> Self

Creates a write buffer

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

Returns the valid portion of the buffer as slice

pub fn reset(&mut self)

Reset the buffer to be reused

pub fn as_str(&self) -> Option<&str>

Converts the buffer in &str, returnig None if some bytes doesn’t resemble valid utf-8

pub fn len(&self) -> usize

Returns the used bytes in the buffer

Trait Implementations

impl<const N: usize> Debug for WriteBuffer<N>

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

Formats the value using the given formatter.

impl<const N: usize> Display for WriteBuffer<N>

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

Formats the value using the given formatter.

impl<const N: usize> Write for WriteBuffer<N>

fn write_str(&mut self, s: &str) -> Result
