Protobuf well-known types for buffa.

This crate provides Rust types for Google's well-known .proto types:

  • [google::protobuf::Timestamp] — Unix timestamp with nanosecond precision
  • [google::protobuf::Duration] — Signed duration with nanosecond precision
  • [google::protobuf::Any] — Any value with an attached type URL
  • [google::protobuf::Struct] / [google::protobuf::Value] / [google::protobuf::ListValue] — JSON-like dynamic values
  • [google::protobuf::FieldMask] — Specifies a subset of fields referenced in a message
  • [google::protobuf::Empty] — A generic empty message
  • Wrapper types: [google::protobuf::BoolValue], [google::protobuf::Int32Value], [google::protobuf::Int64Value], [google::protobuf::UInt32Value], [google::protobuf::UInt64Value], [google::protobuf::FloatValue], [google::protobuf::DoubleValue], [google::protobuf::StringValue], [google::protobuf::BytesValue]

Usage

use buffa_types::google::protobuf::Timestamp;
use buffa::Message;

let ts = Timestamp { seconds: 1_000_000_000, nanos: 0, ..Default::default() };
let bytes = ts.encode_to_vec();
let decoded = Timestamp::decode_from_slice(&bytes).unwrap();
assert_eq!(ts, decoded);

Ergonomic helpers

Common Rust type conversions are provided as trait impls:

  • Timestamp ↔ [std::time::SystemTime] (requires std feature)
  • Duration ↔ [std::time::Duration] (requires std feature)
  • Any::pack / Any::unpack helpers
  • Value constructors: Value::null, From<f64>, From<String>, From<bool>, etc.
  • Wrapper type From/Into impls
