Enum rocket::http::hyper::h1::HttpWriter

pub enum HttpWriter<W> where
    W: Write,  {
    ThroughWriter(W),
    ChunkedWriter(W),
    SizedWriter(W, u64),
    EmptyWriter(W),
}

Writers to handle different Transfer-Encodings.

Variants

ThroughWriter(W)

A no-op Writer, used initially before Transfer-Encoding is determined.

Tuple Fields of ThroughWriter

0: W

ChunkedWriter(W)

A Writer for when Transfer-Encoding includes chunked.

Tuple Fields of ChunkedWriter

0: W

SizedWriter(W, u64)

A Writer for when Content-Length is set.

Enforces that the body is not longer than the Content-Length header.

Tuple Fields of SizedWriter

0: W1: u64

EmptyWriter(W)

A writer that should not write any body.

Tuple Fields of EmptyWriter

0: W

Implementations

impl<W> HttpWriter<W> where
    W: Write, 

pub fn into_inner(self) -> W

Unwraps the HttpWriter and returns the underlying Writer.

pub fn get_ref(&self) -> &W

Access the inner Writer.

pub fn get_mut(&mut self) -> &mut W

Access the inner Writer mutably.

Warning: You should not write to this directly, as you can corrupt the state.

pub fn end(self) -> Result<W, EndError<W>>

Ends the HttpWriter, and returns the underlying Writer.

A final write_all() is called with an empty message, and then flushed. The ChunkedWriter variant will use this to write the 0-sized last-chunk.

Trait Implementations

impl<W> Debug for HttpWriter<W> where
    W: Write, 

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

Formats the value using the given formatter.

impl<W> Write for HttpWriter<W> where
    W: Write, 

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

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

pub fn flush(&mut self) -> Result<(), Error>

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.
