Struct ProtocolRegistry 

pub struct ProtocolRegistry { /* private fields */ }

Registry of built-in protocol decoders.

Implementations

impl ProtocolRegistry

pub fn with_builtins() -> Self

Built-in registry with http and grpc registered.

pub fn http(&self) -> &HttpProtocol

HTTP protocol implementation.

pub fn grpc(&self) -> &GrpcProtocol

gRPC protocol implementation.

pub fn decode_attachment( &self, attachment: &ProtocolAttachment, ) -> Result<DecodedAttachment>

Decode a protocol attachment envelope.

Built-in ids "http" and "grpc" deserialize to DecodedAttachment::Http or DecodedAttachment::Grpc; other ids return DecodedAttachment::Opaque with bytes unchanged.

Examples

use switchback_codec_pb::canardleteer::switchback::protocol::http::v1alpha1::HttpOperationMeta;
use switchback_protocols::{DecodedAttachment, HttpPayloadKind, ProtocolRegistry};

let registry = ProtocolRegistry::with_builtins();
let attachment = registry.http().attach_operation(&HttpOperationMeta {
    method: "GET".into(),
    path_template: "/pets".into(),
    ..Default::default()
});
match registry.decode_attachment(&attachment).unwrap() {
    DecodedAttachment::Http(HttpPayloadKind::Operation(m)) => assert_eq!(m.method, "GET"),
    _ => panic!("expected operation meta"),
}

pub fn http_operation_from_attachments( &self, protocols: &[ProtocolAttachment], ) -> Option<HttpOperationMeta>

Find the first HTTP operation meta on an operation body’s attachments.

pub fn grpc_operation_from_attachments( &self, protocols: &[ProtocolAttachment], ) -> Option<GrpcOperationMeta>

Find the first gRPC operation meta on an operation body’s attachments.
