Crate tarpc_lib

An RPC framework providing client and server.

Features:

• RPC deadlines, both client- and server-side.
• Cascading cancellation (works with multiple hops).
• Configurable limits
  • In-flight requests, both client and server-side.
    • Server-side limit is per-connection.
    • When the server reaches the in-flight request maximum, it returns a throttled error to the client.
    • When the client reaches the in-flight request max, messages are buffered up to a configurable maximum, beyond which the requests are back-pressured.
  • Server connections.
    • Total and per-IP limits.
    • When an incoming connection is accepted, if already at maximum, the connection is dropped.
• Transport agnostic.
