Struct LineDecoder 

pub struct LineDecoder { /* private fields */ }

Incremental newline framer.

Accumulates pushed bytes and yields complete lines split on \n, stripping a single trailing \r from each (so both \n and \r\n framing work). A partial final line with no terminating \n stays buffered across pushes until either a later push completes it or flush is called.

This is the framing half of sim-lib-agent-runner-http’s old per-decoder line_buffer loop, lifted into one shared, tested type.

Implementations

impl LineDecoder

pub fn new() -> Self

Create an empty decoder.

pub fn push(&mut self, bytes: &[u8]) -> Vec<Vec<u8>>

Append bytes and return every line completed by a \n. The trailing \r of a \r\n pair is stripped. Bytes after the last \n remain buffered.

pub fn flush(&mut self) -> Option<Vec<u8>>

Take any buffered remainder (an unterminated final line). Returns None when nothing is buffered. A single trailing \r is stripped to match push.

pub fn buffered_len(&self) -> usize

Number of bytes currently buffered as a partial line.

pub fn buffered(&self) -> &[u8]

Borrow the bytes currently buffered as a partial (unterminated) line.

pub fn has_buffered(&self) -> bool

Whether any partial line is currently buffered.

Trait Implementations

impl Debug for LineDecoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LineDecoder

fn default() -> LineDecoder

Returns the “default value” for a type.
