Enum SyncMode 

pub enum SyncMode {
    Block(&'static [SyncBlock]),
    Interleaved {
        sync_bit_pos: u8,
        vector: &'static [u8],
    },
}

How sync information is carried in the channel symbol stream.

• Block — dedicated contiguous sync blocks (Costas arrays) occupy specific symbol positions, with data symbols filling the rest. Used by FT8, FT4, FST4.
• Interleaved — every channel symbol carries one sync bit (fixed position within the tone index) AND payload bits. The sync bits concatenated across the frame form a known pseudorandom vector. Used by WSPR: tone = 2·data_bit + sync_bit, so LSB of each 4-FSK symbol reproduces the 162-bit npr3 sync vector.

Variants

Block(&'static [SyncBlock])

Interleaved

Fields

sync_bit_pos: u8

Position of the sync bit within the tone index, LSB-first. WSPR = 0 (LSB).

vector: &'static [u8]

Sync vector, one bit per frame symbol. Length == N_SYMBOLS.

Implementations

impl SyncMode

pub const fn blocks(&self) -> &'static [SyncBlock]

Block list for Block mode; empty slice for Interleaved. Sync/LLR/TX helpers that only handle block-structured sync can iterate this unconditionally — they will no-op on WSPR-style protocols, which then need their own interleaved-sync pipeline entry point.
