Implementations

impl<'a> BodyBytesMut<'a>

pub fn reserve(&mut self, len: usize)

pub fn len(&self) -> usize

Returns the length of this body.

pub fn serialize<S>(&mut self, value: &S) -> Result<()>

where S: Serialize + ?Sized,

pub async fn from_file<P>(&mut self, path: P) -> Result<()>

where P: AsRef<Path>,

impl Write for BodyBytesMut<'_>

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

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>
