Struct FrameAccumulator 

pub struct FrameAccumulator<const N: usize> { /* private fields */ }

Byte-by-byte frame accumulator for COBS-framed streams.

Feed raw bytes from the transport via Self::feed. When a 0x00 delimiter is received, Self::frame returns the raw encoded frame bytes ready for decoding.

N is the internal buffer capacity. Frames that exceed N bytes cause the accumulator to discard the current frame and set an overflow flag; Self::frame returns None until Self::reset is called.

Implementations

impl<const N: usize> FrameAccumulator<N>

pub const fn new() -> Self

Create a new, empty accumulator.

pub fn feed(&mut self, byte: u8) -> bool

Feed one byte into the accumulator.

Returns true when a complete frame has been received (i.e., a 0x00 delimiter was just observed). Call Self::frame to get the encoded bytes, then Self::reset before feeding more data.

pub fn frame(&self) -> Option<&[u8]>

Return the accumulated encoded frame bytes.

Returns None if no complete frame is available (overflow or empty accumulator).

pub fn reset(&mut self)

Reset the accumulator, discarding any partial frame.

Trait Implementations

impl<const N: usize> Default for FrameAccumulator<N>

fn default() -> Self

Returns the “default value” for a type.
