Enum Body

pub enum Body<'a> {
    ChunkedBody(&'a mut (dyn Read + 'a)),
    SizedBody(&'a mut (dyn Read + 'a), u64),
    BufBody(&'a [u8], usize),
}

An enum of possible body types for a Request.

Variants

ChunkedBody(&'a mut (dyn Read + 'a))

A Reader does not necessarily know it’s size, so it is chunked.

SizedBody(&'a mut (dyn Read + 'a), u64)

For Readers that can know their size, like a File.

BufBody(&'a [u8], usize)

A String has a size, and uses Content-Length.

Trait Implementations

impl<'a, R: Read> From<&'a mut R> for Body<'a>

fn from(r: &'a mut R) -> Body<'a>

Converts to this type from the input type.

impl<'a> Into<Body<'a>> for &'a [u8]

fn into(self) -> Body<'a>

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

impl<'a> Into<Body<'a>> for &'a String

fn into(self) -> Body<'a>

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

impl<'a> Into<Body<'a>> for &'a str

fn into(self) -> Body<'a>

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

impl<'a> Read for Body<'a>

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, Error>

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.

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

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

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

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

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Reads the exact number of bytes required to fill cursor.

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

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

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

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

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

where Self: Sized,

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