Struct ToolResultMetadata 

pub struct ToolResultMetadata {
    pub tool_id: String,
    pub version: Option<String>,
    pub binding: Option<BindingProtocol>,
    pub latency_ms: Option<u64>,
    pub timestamp: Option<String>,
    pub request_id: Option<String>,
}

Metadata attached to a successful tool result.

Only tool_id is required — servers always echo it. All other fields are server-populated and optional: clients must not synthesize them, because a fabricated timestamp/request_id would silently masquerade as server truth. timestamp and request_id are kept as opaque strings so this crate has no dependency on a specific datetime or ULID implementation; callers that need typed access can parse with their preferred library.

Fields

tool_id: String

version: Option<String>

binding: Option<BindingProtocol>

latency_ms: Option<u64>

timestamp: Option<String>

ISO-8601 / RFC-3339 timestamp, server-populated.

request_id: Option<String>

Opaque request identifier (ULID, UUID, or whatever the server emits).

Implementations

impl ToolResultMetadata

pub fn for_tool(tool_id: impl Into<String>) -> Self

Construct minimal metadata with only tool_id set. The canonical way for clients to create metadata — everything else is for the server to fill in.

fn clone(&self) -> ToolResultMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
