## 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.

// offset that is not in the range [0,2^32-1], but it will generate
// `OUT_OF_RANGE` if asked to read from an offset past the current
// file size.
//
// There is a fair bit of overlap between `FAILED_PRECONDITION` and
// `OUT_OF_RANGE`. We recommend using `OUT_OF_RANGE` (the more specific
