Struct StreamEncoder 

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

Encoder for one direction of one logical session.

Implementations

impl StreamEncoder

pub fn new(encoding: StreamEncoding) -> Result<Self, StreamEncodingError>

Fresh encoder at the default level: deflate 9, zstd 3.

pub fn with_level( encoding: StreamEncoding, level: i32, ) -> Result<Self, StreamEncodingError>

Fresh encoder at a sender-chosen level. The decoder needs only the encoding. Identity ignores the level.

pub fn encode( &mut self, input: &[u8], mode: EncodeMode, output: &mut [u8], ) -> Result<EncodeProgress, StreamEncodingError>

Encode a prefix of input into at most output.len() bytes.

Write takes plaintext, Flush completes all plaintext written so far so the peer can decode it from the wire bytes alone (every batch end), and End writes the end mark, after which the encoder takes nothing more. Callers repeat a step with fresh output room until it is done; a flushing step needs at least ENCODE_MIN_OUTPUT bytes of room.

pub fn is_identity(&self) -> bool

Whether this encoder passes plaintext through unchanged.
