Crate async_proto

This is async-proto, a library crate facilitating simple binary network protocols with async support.

The main feature is the Protocol trait, which allows reading a value of an implementing type from an async or sync stream, as well as writing one to an async or sync sink.

Protocol can be derived for enums and structs if all fields implement Protocol.

Features

This crate offers optional dependencies on the following crates to enable Protocol implementations for some of their types:

• bytes: Bytes
• chrono: NaiveDate, DateTime, Utc, and FixedOffset
• chrono-tz: Tz
• either: Either
• enumset: EnumSet
• git2: Oid
• noisy_float: NoisyFloat
• semver: Version, Prerelease, and BuildMetadata
• serde_json: Value, Map, and Number
• uuid: Uuid

Additionally, the following features can be enabled via Cargo:

• tokio-tungstenite: Adds a dependency on the tokio-tungstenite crate and convenience methods for reading/writing Protocol types from/to its websockets.
• tungstenite: Adds a dependency on the tungstenite crate and convenience methods for synchronously reading/writing Protocol types from/to its websockets.
• warp: Adds a dependency on the warp crate and convenience methods for reading/writing Protocol types from/to its websockets.

Macros

• bitflags
  Implements Protocol for a type defined using the bitflags::bitflags macro.

Structs

• ReadError
  The error returned from the read and read_sync methods.
• WriteError
  The error returned from the write and write_sync methods.

Enums

• ErrorContext
  Provides additional information about the origin of an error.
• ReadErrorKind
  Specifies what went wrong while reading (receiving) a value.
• WriteErrorKind
  Specifies what went wrong while writing (sending) a value.

Traits

• Protocol
  This trait allows reading a value of an implementing type from an async or sync stream, as well as writing one to an async or sync sink.

Functions

• websockettokio-tungstenite
  Establishes a WebSocket connection to the given URL and returns a typed sink/stream pair.

Derive Macros

• Protocol
  Implements the Protocol trait for this type.
