Struct BytesWriter

pub struct BytesWriter { /* private fields */ }

Wrapper over bytes::BytesMut with convenient io::Write interface

Automatically allocates instead of returning error.

Implementations

impl BytesWriter

pub fn with_capacity(capacity: usize) -> Self

Creates new instance with provided capacity

pub fn freeze(self) -> Bytes

Converts to bytes::Bytes

Trait Implementations

impl Default for BytesWriter

fn default() -> Self

Returns the “default value” for a type.

impl Into<Bytes> for BytesWriter

fn into(self) -> Bytes

Converts this type into the (usually inferred) input type.

impl Write for BytesWriter

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

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

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

Attempts to write an entire buffer into this writer.

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_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.

impl Write for BytesWriter

fn write_str(&mut self, text: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

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

Glue for usage of the write! macro with implementors of this trait.
