Struct FixedBytes

pub struct FixedBytes<const N: usize, E = FixedBytesWriterError> { /* private fields */ }

A fixed-size bytes storage which keeps track of how much has been initialized.

Implementations

impl<const N: usize, E> FixedBytes<N, E>

pub const fn new() -> Self

Construct a new fixed bytes array storage.

pub const fn len(&self) -> usize

Get the length of the collection.

pub fn into_bytes(self) -> Option<[u8; N]>

Coerce into the underlying bytes if all of them have been initialized.

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

Coerce into the slice of initialized memory which is present.

Trait Implementations

impl<const N: usize, E> Writer for FixedBytes<N, E>

where E: Error,

type Error = E

The error type raised by the writer.

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

Write bytes to the current writer.

fn write_byte(&mut self, b: u8) -> Result<(), Self::Error>

Write a single byte.

fn write_array<const N: usize>( &mut self, array: [u8; N], ) -> Result<(), Self::Error>

Write an array to the current writer.
