Struct DecoderReader 

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

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

For padded engines, this reader stops at the terminal padded Base64 block and leaves later bytes unread in the wrapped reader. This preserves boundaries for callers that decode one Base64 payload from a larger stream.

Implementations

impl<R, A, const PAD: bool> DecoderReader<R, A, PAD>

where A: Alphabet,

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

Creates a new streaming decoder reader.

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

Returns a shared reference to the wrapped reader.

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

Returns a mutable reference to the wrapped reader.

pub fn into_inner(self) -> R

Consumes the decoder reader and returns the wrapped reader.

Trait Implementations

impl<R, A, const PAD: bool> Read for DecoderReader<R, A, PAD>

where R: Read, A: Alphabet,

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

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

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

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

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Reads the exact number of bytes required to fill cursor.

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

where Self: Sized,

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

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

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

where Self: Sized,

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

Read and return a fixed array of bytes from this source.
