pub struct LengthDelimitedCodec { /* private fields */ }
Expand description

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.

Implementations§

source§

impl LengthDelimitedCodec

source

pub fn new() -> Self

Creates a new LengthDelimitedCodec with the default configuration values.

source

pub fn builder() -> Builder

Creates a new length delimited codec builder with default configuration values.

source

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.

source

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.
