prost-types 0.14.1

Prost definitions of Protocol Buffers well known types.
Documentation
#![doc(html_root_url = "https://docs.rs/prost-types/0.14.1")]

//! Protocol Buffers well-known types.
//!
//! Note that the documentation for the types defined in this crate are generated from the Protobuf
//! definitions, so code examples are not in Rust.
//!
//! See the [Protobuf reference][1] for more information about well-known types.
//!
//! ## Any
//!
//! The well-known [`Any`] type contains an arbitrary serialized message along with a URL that
//! describes the type of the serialized message. Every message that also implements [`Name`]
//! can be serialized to and deserialized from [`Any`].
//!
//! ### Serialization
//!
//! A message can be serialized using [`Any::from_msg`].
//!
//! ```rust
//! let message = Timestamp::date(2000, 1, 1).unwrap();
//! let any = Any::from_msg(&message).unwrap();
//! ```
//!
//! ### Deserialization
//!
//! A message can be deserialized using [`Any::to_msg`].
//!
//! ```rust
//! # let message = Timestamp::date(2000, 1, 1).unwrap();
//! # let any = Any::from_msg(&message).unwrap();
//! #
//! let message = any.to_msg::<Timestamp>().unwrap();
//! ```
//!
//! ## Feature Flags
//! - `std`: Enable integration with standard library. Disable this feature for `no_std` support. This feature is enabled by default.
//! - `arbitrary`: Enable integration with crate `arbitrary`. All types on this crate will implement `trait Arbitrary`.
//! - `chrono`: Enable integration with crate `chrono`. Time related types implement conversions to/from their `chrono` equivalent.
//!
