[−][src]Struct tokio::codec::length_delimited::LengthDelimitedCodec
A codec for frames delimited by a frame head specifying their lengths.
This allows the consumer to work with entire frames without having to worry about buffering or other framing logic.
See module level documentation for more detail.
Methods
impl LengthDelimitedCodec
[src]
impl LengthDelimitedCodec
pub fn new() -> Self
[src]
pub fn new() -> Self
Creates a new LengthDelimitedCodec
with the default configuration values.
pub fn max_frame_length(&self) -> usize
[src]
pub fn max_frame_length(&self) -> usize
Returns the current max frame setting
This is the largest size this codec will accept from the wire. Larger frames will be rejected.
pub fn set_max_frame_length(&mut self, val: usize)
[src]
pub fn set_max_frame_length(&mut self, val: usize)
Updates the max frame setting.
The change takes effect the next time a frame is decoded. In other
words, if a frame is currently in process of being decoded with a frame
size greater than val
but less than the max frame length in effect
before calling this function, then the frame will be allowed.
