Struct FinalRequestMeta 

pub struct FinalRequestMeta {
    pub protocol_version: String,
    pub client_capabilities: ClientCapabilities,
    pub client_info: Option<Implementation>,
    pub additional_metadata: BTreeMap<String, Value>,
}

Required final metadata carried in the _meta object of every request.

The protocol version and client capabilities are intentionally distinct from legacy RequestMeta. Final request admission validates the version against the HTTP header before using the advertised capabilities.

Fields

protocol_version: String

The exact protocol revision selected for this request.

client_capabilities: ClientCapabilities

Capabilities advertised by the request’s client.

client_info: Option<Implementation>

Optional client identity supplied on this request.

additional_metadata: BTreeMap<String, Value>

Additional metadata retained without granting protocol capability.

Implementations

impl FinalRequestMeta

pub fn new(client_capabilities: ClientCapabilities) -> Self

Creates canonical metadata for the exact final protocol version.

pub fn version_metadata<'a>( &'a self, header_version: Option<&'a str>, ) -> RequestVersionMetadata<'a>

Returns the protocol header/body mirror for final request admission.
