Struct pb_jelly::CopyWriter

pub struct CopyWriter<'a, W: Write> {
    pub writer: &'a mut W,
}

A wrapper around a Write which copies all the data into the underlying Writer.

Fields

writer: &'a mut W

Trait Implementations

impl<'a, W: Write + 'a> PbBufferWriter for CopyWriter<'a, W>

pub fn write_buffer<B: PbBuffer>(&mut self, buf: &B) -> Result<()>

Note: this implementation freely copies the data out of buf.

impl<'a, W: Write + 'a> Write for CopyWriter<'a, W>

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

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

pub 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.
