Struct EncodeWriter 

pub struct EncodeWriter<W: Write, const N: usize> { /* private fields */ }

A buffered writer that encodes raw bytes before writing them to an inner writer.

This writer buffers input bytes, encodes them using the specified Encoding<N>, and writes the encoded output to the wrapped writer. It implements io::Write, allowing transparent encoding of data streams.

Examples

use std::io::Write;

use omp_core::encoding::{EncodeWriter, base64};

let mut output = Vec::new();
let mut writer = base64::encode_writer(&mut output);
writer.write_all(b"Hello, World!").unwrap();
writer.flush().unwrap();
// output now contains base64-encoded data

Implementations

impl<W: Write, const N: usize> EncodeWriter<W, N>

pub const fn new(inner: W, enc: Encoding<N>) -> Self

Creates a new encoding writer that wraps the given writer.

pub fn into_inner(self) -> Result<W>

Consumes this writer, flushing any buffered data and returning the inner writer.

Errors

Returns an error if flushing fails.

Trait Implementations

impl<W: Write, const N: usize> Drop for EncodeWriter<W, N>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<W: Write, const N: usize> Write for EncodeWriter<W, N>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
