Struct CatalogClientContract 

pub struct CatalogClientContract {
    pub protocol_version: i64,
    pub required_capabilities: Vec<String>,
}

The protocol version and capability set a caller requires, supplied on every catalog request so negotiation cannot be skipped by omission.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

protocol_version: i64

SDK protocol version the caller was generated against. A caller below the runtime’s minimum supported version is refused rather than served a partial result.

required_capabilities: Vec<String>

Wire features the caller requires the runtime to understand. Identifiers are bounded but extensible so a newer caller can negotiate with an older runtime. Requiring an unknown feature yields a typed refusal listing what is understood, never a partial grant. A grant does not promise that a deployment has enabled the operation; typed unavailable results report that separately.
