Struct Limits 

pub struct Limits {
    pub max_payload_bytes: u64,
    pub max_embedded_bytes: u64,
    pub idempotency_key_ttl_seconds: Option<u32>,
    pub max_publish_per_minute: Option<u64>,
}

Resource limits declared by the registry.

The capabilities document is OPEN at the top level, but limits is a CLOSED sub-object (additionalProperties: false): new limit keys are added by a spec version bump, not by registries inventing fields, so deny_unknown_fields rejects an unknown key (RFC-ACDP-0007 §3.3.1, conformance fixture schema-010).

Fields

max_payload_bytes: u64

Maximum total publish request size in bytes.

max_embedded_bytes: u64

Maximum size of any single embedded data reference in bytes (≤ 65536).

idempotency_key_ttl_seconds: Option<u32>

How long idempotency-key mappings are retained, in seconds. MUST be present when supports_idempotency_key is true.

Optional and absent-or-integer in the schema — not nullable. de_present rejects an explicit "idempotency_key_ttl_seconds": null.

max_publish_per_minute: Option<u64>

(0.3.0) OPTIONAL nominal per-agent publish ceiling, in publishes per minute (integer ≥ 1). Advisory: producers SHOULD use it to pace publishes; its presence does NOT change the RFC-ACDP-0008 §4.3 requirements (rate limiting stays REQUIRED, Retry-After stays mandatory on 429). RFC-ACDP-0007 §3.2, fixture caps-007.
