Crate awp_types 

awp-types

Shared protocol types for the Agentic Web Protocol (AWP).

This crate provides pure protocol types with zero adk-* dependencies, making it importable by any Rust project that needs to work with AWP messages.

Types

• AwpVersion / CURRENT_VERSION — protocol version with compatibility checks
• TrustLevel — request trust classification (Anonymous, Known, Partner, Internal)
• RequesterType — human vs. agent requester distinction
• AwpError — structured error codes with HTTP status mapping
• AwpRequest / AwpResponse — protocol request/response envelopes
• A2aMessage / A2aMessageType — agent-to-agent communication
• AwpDiscoveryDocument — well-known discovery endpoint payload
• CapabilityManifest / CapabilityEntry — JSON-LD capability descriptions
• BusinessContext / BusinessCapability / BusinessPolicy — site configuration
