Struct fastly::Body

pub struct Body { /* fields omitted */ }

An HTTP body that can be read from, written to, or appended to another body.

The most efficient way to read and write the body is through the Read, BufRead, and Write implementations.

Implementations

impl Body

pub fn new() -> Self

Get a new, empty HTTP body.

pub fn into_handle(self) -> BodyHandle

Convert a Body into a BodyHandle.

pub fn into_bytes(self) -> Vec<u8>

Read the entirety of the body.

Note that this will involve copying and buffering the body, and so should only be used for convenience on small request bodies.

pub fn into_string(self) -> String

Read the entirety of the body into a String, interpreting the bytes as UTF-8.

Note that this will involve copying and buffering the body, and so should only be used for convenience on small request bodies.

pub fn append(&mut self, other: Body)

Append another body onto the end of this body.

pub fn write_bytes(&mut self, bytes: &[u8]) -> usize

Write a slice of bytes to the end of this Body.

This function returns the number of bytes written.

body.write_bytes(&[0, 1, 2, 3]);

pub fn write_str(&mut self, string: &str) -> usize

Write a string slice to the end of this Body.

This function returns the number of bytes written.

body.write_str("woof woof");

Trait Implementations

impl BufRead for Body

fn fill_buf(&mut self) -> Result<&[u8]>

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(&mut self, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to read.

fn read_until(&mut self, byte: u8, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes into buf until the delimiter byte or EOF is reached.

fn read_line(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided buffer.

fn split(self, byte: u8) -> Split<Self>

Returns an iterator over the contents of this reader split on the byte byte.

fn lines(self) -> Lines<Self>

Returns an iterator over the lines of this reader.

impl Debug for Body

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

Formats the value using the given formatter.

impl<'_> From<&'_ [u8]> for Body

fn from(s: &[u8]) -> Self

Performs the conversion.

impl<'_> From<&'_ str> for Body

fn from(s: &str) -> Self

Performs the conversion.

impl From<BodyHandle> for Body

fn from(handle: BodyHandle) -> Self

Performs the conversion.

impl From<String> for Body

fn from(s: String) -> Self

Performs the conversion.

impl From<Vec<u8>> for Body

fn from(s: Vec<u8>) -> Self

Performs the conversion.

impl Read for Body

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

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

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

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl Write for Body

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

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

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

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

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

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

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writeer 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" adaptor for this instance of Write.
