Struct Codec 

pub struct Codec { /* private fields */ }

Frame-level codec for \r-terminated CAT protocol messages.

Buffers incoming bytes and emits complete frames. Handles partial reads gracefully — the radio may send responses in multiple chunks.

Implementations

impl Codec

pub const fn new() -> Self

Creates a new codec with an empty buffer.

pub fn feed(&mut self, data: &[u8])

Appends raw bytes to the internal buffer.

If the buffer would exceed 64 KB, it is truncated to prevent unbounded memory growth.

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

Extracts the next complete frame from the buffer, if available.

Searches for a \r delimiter, extracts everything before it as a frame (without the trailing \r), and removes the consumed bytes from the buffer. Returns None if no complete frame is available.

Trait Implementations

impl Debug for Codec

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

Formats the value using the given formatter.

impl Default for Codec

fn default() -> Self

Returns the “default value” for a type.
