Struct StreamResponse 

pub struct StreamResponse {
    pub body: StreamResponseBody,
    pub slash_sig: Vec<u8>,
}

Node → payer response to a StreamRequest (ADR 005 §cdn/client/v1).

This struct holds only the frozen base (ADR 013 §Tier 1): the signed StreamResponseBody and the slash_sig covering it. Unsigned fields live in StreamResponseExt, which travels as separate trailing bytes — see encode_stream_response / parse_stream_response_ext.

slash_sig is mandatory and non-empty (exactly SLASH_SIG_LEN bytes); requesters MUST reject missing/zero-length or zero-rate_per_mb responses (enforced via StreamResponse::validate).

Fields

body: StreamResponseBody

Signed body. Its wire layout is frozen per ADR 013.

slash_sig: Vec<u8>

EIP-712 secp256k1 signature over body’s signed fields (ADR 014 §1; produced by the decdn_incentive stream slash signer, analogous to its ProbeSlashData). Always exactly SLASH_SIG_LEN bytes — not a signature over postcard bytes.

Implementations

impl StreamResponse

pub const fn validate(&self) -> Result<(), MessageValidationError>

Validate requester-side invariants (ADR 005, ADR 014 §1, #252):

• rate_per_mb within (0, MAX_RATE_PER_MB] (the decode path already enforces the upper bound via deserialize_rate_per_mb; this adds the zero-rate rule),
• slash_sig exactly SLASH_SIG_LEN bytes.

The ok/error consistency rule is NOT here: error lives in StreamResponseExt, which this method cannot see. A receiver must also call StreamResponseExt::validate with body.ok.

Exposed so requesters re-check on receive and construction sites assert validity before signing.
