Network.Transport.InMemory

In-memory implementation of the Transport API.

Documentation

createTransport :: IO Transport

Create a new Transport.

Only a single transport should be created per Haskell process (threads can, and should, create their own endpoints though).

createTransportExposeInternals :: IO (Transport, TransportInternals)

Create a new Transport exposing internal state.

Useful for testing and/or debugging purposes. Should not be used in production. No guarantee as to the stability of the internals API.

For testing purposes

newtype TransportInternals

Constructors

TransportInternals (TVar TransportState)

breakConnection

Arguments

:: TransportInternals

-> EndPointAddress

-> EndPointAddress

-> String

Error message

-> IO ()

Function that simulate failing connection between two endpoints, after calling this function both endpoints will receive ConnectionEventLost message, and all LocalConnectionValid connections will be put into LocalConnectionFailed state.
