Struct I18nReader 

pub struct I18nReader<R: Read> { /* private fields */ }

Reader for non-UTF-8 input sources. Although this is mainly for non-UTF-8, reads the input source with zero overhead if no transcoding is needed

Implementations

impl<R: Read> I18nReader<R>

pub fn new(reader: R, transcoder: Transcoder) -> Self

Creates a new I18nReader. Transcoder needs to have the source encoding. If the source encoding can’t be known in advance, use I18nReaderEncodingDetector.

pub fn had_replacement_or_unmappable(&self) -> bool

Whether replacement characters or unmappable characters are seen so far.

Trait Implementations

impl<R: Read> Read for I18nReader<R>

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

Reads the input using the specified source encoding and transcode to UTF-8 or the specified destination encoding.

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” adaptor 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.
