Struct Body 

pub struct Body(/* private fields */);

The trillium representation of a http body. This can contain either &'static [u8] content, Vec<u8> content, or a boxed AsyncRead/BodySource type.

Implementations

impl Body

pub fn new_streaming( async_read: impl AsyncRead + Send + 'static, len: Option<u64>, ) -> Body

Construct a new body from a streaming AsyncRead source. If you have the body content in memory already, prefer Body::new_static or one of the From conversions.

pub fn new_with_trailers(body: impl BodySource, len: Option<u64>) -> Body

Construct a new body from a BodySource that can produce trailers after the body has been fully read.

Use this when trailers must be computed dynamically from the body bytes, for example to append a content hash.

pub fn new_static(content: impl Into<Cow<'static, [u8]>>) -> Body

Construct a fixed-length Body from a Vec<u8> or &'static [u8].

pub fn static_bytes(&self) -> Option<&[u8]>

Retrieve a borrow of the static content in this body. If this body is a streaming body or an empty body, this will return None.

pub fn into_reader(self) -> Pin<Box<dyn AsyncRead + Sync + Send>>

Transform this Body into a dyn AsyncRead. This will wrap static content in a Cursor. Note that this is different from reading directly from the Body, which includes chunked encoding.

pub async fn into_bytes(self) -> Result<Cow<'static, [u8]>, Error>

Consume this body and return the full content. If the body was constructed with Body::new_streaming, this will read the entire streaming body into memory, awaiting the streaming source’s completion. This function will return an error if a streaming body has already been partially or fully read.

Errors

This returns an error variant if either of the following conditions are met:

there is an io error when reading from the underlying transport such as a disconnect the body has already been read to completion

pub fn bytes_read(&self) -> u64

Retrieve the number of bytes that have been read from this body

pub fn len(&self) -> Option<u64>

returns the content length of this body, if known and available.

pub fn is_empty(&self) -> bool

determine if the this body represents no data

pub fn is_static(&self) -> bool

determine if the this body represents static content

pub fn is_streaming(&self) -> bool

determine if the this body represents streaming content

Trait Implementations

impl AsyncRead for Body

fn poll_read( self: Pin<&mut Body>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>
