Struct FrameSync 

pub struct FrameSync<'a> { /* private fields */ }

A frame synchronizer that searches for ASM patterns in a byte stream to locate frame boundaries.

This implements a simple byte-aligned ASM search suitable for simulation. A real receiver would do bit-level correlation with an allowable bit-error threshold.

Implementations

impl<'a> FrameSync<'a>

pub fn new(asm: &'a [u8], frame_len: usize) -> Self

Creates a new frame synchronizer.

• asm: the sync marker pattern to search for
• frame_len: expected frame length excluding the ASM

pub fn cadu_len(&self) -> usize

Returns the total CADU length (ASM + frame).

pub fn find_frame<'b>(&self, data: &'b [u8]) -> Option<(usize, &'b [u8])>

Searches data for the next ASM-aligned frame.

Returns Some((offset, frame)) where offset is the byte position of the ASM in data and frame is the frame payload (after the ASM). Returns None if no complete frame is found.

pub fn find_all_frames<'b>(&'b self, data: &'b [u8]) -> FrameIter<'b>

Finds all ASM-aligned frames in data.

Returns an iterator of (offset, frame_slice) pairs. Frames may overlap if the data contains spurious ASM matches; callers should validate frame contents.
