Synopsis

data EventlogSource
data Tick a
- = Item !a

Documentation

data EventlogSource Source #

The type of eventlog sockets.

Constructors

EventlogStdin
EventlogFile FilePath
EventlogSocketUnix FilePath

data Tick a Source #

The type of data on a stream of items and ticks.

The Tick type is isomorphic to Maybe modulo strictness, but with the caveat that Tick does not represent failure.

Constructors

Item !a
Tick
