sdr-stream

DigitalStream — the record container behind MimoSDR's .sdr call files, its WebSocket messages and its future WebRTC datagrams: one framing for all three. no_std + alloc, zero dependencies, permanently: a wire format needs nothing but bytes.

• Framing (format v1): a 32-byte head — magic sdr\0, version, type, length in bytes, epoch µs, Hz, sequence, NAC, flags, site — then the body; readers advance by length, ignore tails, keep unknown types raw.
• The mode-neutral records: CallHeader, Ess (encryption sync), CallTrailer.
• The P25 layouts (p25: LDU, Phase 2 VCH) and the DMR layouts (dmr: voice, Full LC + lc_info, packet, fix, alias).
• The sidecar document (sidecar): a projection of a call's records, or the MSDR chunk of an analog WAV (riff).
• The filename grammar (name), so a server names what it stores from the record, never from a client's filename.
• Dependency-free JSON (json).

The full specification is the crate documentation in src/lib.rs.

This repository is a tree export of crates/stream in the private mimosdr repository, published as one commit per release; the same bytes also ship inside github.com/MimoCAD/sdr-decode. Consumers pin a git rev:

stream = { package = "sdr-stream", git = "https://github.com/MimoCAD/sdr-stream.git", rev = "…" }
