Struct mla::helpers::StreamWriter

pub struct StreamWriter<'a, 'b, W: Write> { /* fields omitted */ }

Provides a Write interface on an ArchiveWriter file

This interface is meant to be used in situations where length of the data source is unknown, such as a stream. One can then use the io::copy facilities to perform multiples block addition in the archive

Implementations

impl<'a, 'b, W: Write> StreamWriter<'a, 'b, W>

pub fn new(
    archive: &'b mut ArchiveWriter<'a, W>,
    file_id: ArchiveFileID
) -> Self

Trait Implementations

impl<'a, 'b, W: Write> Write for StreamWriter<'a, 'b, W>

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

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

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

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

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

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

pub 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.

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

Attempts to write an entire buffer into this writer.

pub 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.

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

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

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

Creates a "by reference" adaptor for this instance of Write.
