Struct Decoder 

pub struct Decoder<W, A, const PAD: bool>
where
    A: Alphabet,
{ /* private fields */ }

A streaming Base64 decoder for std::io::Write.

Implementations

impl<W, A, const PAD: bool> Decoder<W, A, PAD>

where A: Alphabet,

pub const fn new(inner: W, engine: Engine<A, PAD>) -> Self

Creates a new streaming decoder.

pub const fn get_ref(&self) -> &W

Returns a shared reference to the wrapped writer.

pub fn get_mut(&mut self) -> &mut W

Returns a mutable reference to the wrapped writer.

pub fn into_inner(self) -> W

Consumes the decoder without flushing pending input.

Prefer Self::finish when the decoded output must be complete.

impl<W, A, const PAD: bool> Decoder<W, A, PAD>

where W: Write, A: Alphabet,

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

Validates final pending input, flushes the wrapped writer, and returns it.

Trait Implementations

impl<W, A, const PAD: bool> Write for Decoder<W, A, PAD>

where W: Write, A: Alphabet,

fn write(&mut self, input: &[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.
