Crate grpc_core 

Synchronous, codec-independent gRPC contracts.

Message envelopes and codec interfaces are available independently of a transport. Aligned message framing, bounded compression, statuses and metadata support transport-independent RPC message handling.

Per-message compression and grpc-accept-encoding negotiation.

framing

Incremental gRPC framing with eight-byte-aligned message payloads.

http2

Sans-IO streaming HTTP/2 with independent connection and stream flow control.

metadata

Validated application metadata with raw binary values.

method

Static RPC routing and cardinality descriptions.

request

Request messages and their application metadata.

response

Response messages and their initial application metadata.

session

Synchronous HTTP/2 gRPC sessions with bounded per-stream receive and send queues.

slot_map

Bounded, single-threaded ownership of HTTP/2 stream receive events.

status

Canonical gRPC status codes and their HTTP/2 trailer representation.

tls

Synchronous rustls transports with authenticated HTTP/2 ALPN negotiation.

transport

Synchronous byte transports for blocking callers and externally driven event loops.
