Barter-Integration

High-performance, low-level framework for composing flexible web integrations.

Utilised by other Barter trading ecosystem crates to build robust financial exchange integrations, primarily for public data collection & trade execution. It is:

• Low-Level: Translates raw data streams communicated over the web into any desired data model using arbitrary data transformations.
• Flexible: Compatible with any protocol (WebSocket, FIX, Http, etc.), any input/output model, and any user defined transformations.

Core abstractions:

• RestClient providing configurable signed Http communication between client & server.
• ExchangeStream providing configurable communication over any asynchronous stream protocols (WebSocket, FIX, etc.).

Both core abstractions provide the robust glue you need to conveniently translate between server & client data models.

Modules

• de
  Utilities to assist deserialisation.
• error
  All Errors generated in Barter-Integration.
• metric
  Contains the flexible Metric type used for representing real-time metrics generically.
• model
  Foundational data structures that define the building blocks used by the rest of the Barter ecosystem.
• protocol
  Contains StreamParser implementations for transforming communication protocol specific messages into a generic output data structure.

Structs

• ExchangeStream
  An ExchangeStream is a communication protocol agnostic Stream. It polls protocol messages from the inner Stream, and transforms them into the desired output data structure.

Traits

• Transformer
  Transformers are capable of transforming any Input into an iterator of Result<Self::Output, Self::Error>s.
• Validator
  Validators are capable of determining if their internal state is satisfactory to fulfill some use case defined by the implementor.
