## RPC (Remote Procedure Call) Types
|
||
|
|
|
||
|
|
This package contains [protocol buffer][protobuf] types that represent remote procedure
|
||
|
|
call concepts. While [gRPC](https://grpc.io) uses these types, we encourage their
|
||
|
|
use in any interested RPC implementation to promote compatibility and consistency.
|
||
|
|
|
||
|
|
### Key Concepts
|
||
|
|
|
||
|
|
- **Code**: An enum that represents an error code returned by an RPC. These error codes
|
||
|
|
map to HTTP codes, but are slightly finer-grained. Every gRPC code has exactly one
|
||
|
|
corresponding HTTP code; however, some HTTP codes have more than one corresponding
|
||
|
|
gRPC code.
|
||
|
|
- **Error details**: Any of the types contained in `error_details.proto` which provide
|
||
|
|
extra details about particular types of failures.
|
||
|
|
- **Status**: Combines a code, message, and error details to represent the success or
|
||
|
|
failure details of an RPC call.
