Struct witchcraft_server::blocking::ResponseWriter

pub struct ResponseWriter { /* private fields */ }

The writer used for streaming response bodies of blocking endpoints.

Implementations

impl ResponseWriter

pub fn send(&mut self, bytes: Bytes) -> Result<(), Error>

Writes a block of Bytes to the response body.

Compared to ResponseWriter’s Write implementation, this method can avoid some copies if the data is already represented as a Bytes value.

pub fn send_trailers(&mut self, trailers: HeaderMap) -> Result<(), Error>

Writes the response’s trailers.

The body must be fully written before calling this method.

Trait Implementations

impl Write for ResponseWriter

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.

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

Attempts to write an entire buffer into this writer.

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, fmt: Arguments<'_>) -> Result<(), Error>

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

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

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