Module envelope 

Stream boundary contract: the StreamEnvelope that wraps every packet crossing the streaming fabric.

An envelope binds a StreamPacket to the routing and timing metadata a transport needs to carry it: the originating stream and packet ids, the media and direction, a monotonic sequence number, the Ticks that locate it on its clocks, the ClockDomains it rides, the TransportProfile that bounds what the transport may do, and any diagnostics raised along the way.

The kernel owns the protocol vocabulary referenced here – Symbol, Expr, Tick, and the clock/capability contracts. This module supplies the concrete envelope behavior: construction with validation, the wire form (StreamEnvelope::to_expr / TryFrom<Expr>), and the mapping of clock-domain symbols to the ClockDomain enum.

Structs

StreamEnvelope

A single packet plus the routing and timing metadata that carries it across the streaming fabric.

TransportProfile

The capability and latency contract a transport offers for a stream.

Enums

ClockDomain

Clock a stream is timed against.

LatencyClass

Real-time latency promise a transport profile makes.

StreamCapability

One thing a transport is permitted to do with a stream.

Constants

STREAM_ENVELOPE_VERSION

Wire version of the StreamEnvelope map form.

Functions

stream_envelope_tag_symbol

Returns the runtime tag Symbol that marks a map as a stream envelope.
