[−][src]Struct fastly::http::body::StreamingBody
A streaming HTTP body that can be written to, or appended to from another body.
The interface to this type is very similar to Body
, however it is write-only, and can only be
created as a result of calling
Response::stream_to_client()
or
Request::send_async_streaming()
.
The most efficient way to write the body is through the Write
implementation. Writes are
buffered, and automatically flushed, but you can call Write::flush()
to explicitly flush the
buffer and cause a new chunk to be written to the client.
A streaming body will be automatically closed when it goes out of scope, or when it is passed to
drop()
.
Implementations
impl StreamingBody
[src]
pub fn append(&mut self, other: Body)
[src]
Append a body onto the end of this streaming body.
This operation is performed in amortized constant time, and so should always be preferred to reading an entire body and then writing the same contents to another body.
Examples
let mut streaming_body = beresp.stream_to_client(); streaming_body.append(other_body);
pub fn write_bytes(&mut self, bytes: &[u8]) -> usize
[src]
Write a slice of bytes to the end of this streaming body, and return the number of bytes written.
Examples
let mut streaming_body = resp.stream_to_client(); streaming_body.write_bytes(&[0, 1, 2, 3]);
pub fn write_str(&mut self, string: &str) -> usize
[src]
Write a string slice to the end of this streaming body, and return the number of bytes written.
Examples
let mut streaming_body = resp.stream_to_client(); streaming_body.write_str("woof woof");
