Expand description

State tracked for a single multiplexed stream.

Fields§

§id: SpsStreamId

Unique stream identifier.

§priority: u32

Scheduling priority (higher = more important; 255 is highest).

§weight: u32

Relative weight used for proportional-share policies.

§pending_bytes: u64

Number of bytes waiting to be sent.

§deficit_counter: i64

DRR deficit counter (may be negative after a partial send).

§send_count: u64

Total number of scheduling events for this stream.

§bytes_sent: u64

Total bytes transmitted so far.

§last_scheduled_ts: u64

Timestamp (monotonic, arbitrary epoch) of the last scheduling event.

§is_blocked: bool

If true the stream is temporarily suspended and will not be scheduled.

§deadline: u64

Optional deadline value (lower = more urgent; used by EDF policy).

§htb_tokens: i64

Token bucket for HTB policy: current token balance in bytes.

§htb_rate: u64

Token refill rate in bytes per “tick” for HTB.

§htb_burst: u64

Maximum burst size in bytes for HTB.
