Polysemy.Time

Description

This package provides a Polysemy effect for interacting with the current time and sleeping, as well as some time-related data types and classes.

Synopsis

data Time (time :: Type) (date :: Type) :: Effect where Source #

The Time effect.

Constructors

Now :: Time t d m t

Produce the current time, possibly relative to what was set with SetTime or SetDate

Today :: Time t d m d

Produce the current date, possibly relative to what was set with SetTime or SetDate

Sleep :: TimeUnit u => u -> Time t d m ()

Suspend the current computation for the specified time span.

SetTime :: t -> Time t d m ()

Set the current time, if the interpreter supports it.

Adjust :: AddTimeUnit t u1 u2 => u1 -> Time t d m ()

Adjust the current time relatively, if the interpreter supports it.

SetDate :: d -> Time t d m ()

Set the current date, if the interpreter supports it.

measure :: forall dt t d u r a. TimeUnit u => Torsor dt u => Instant t dt => Member (Time t d) r => Sem r a -> Sem r (u, a) Source #

Run the action ma and measure the time it takes.

The type of the difference depends on the functional dependencies of the classes Instant and Torsor, where the input to the former is taken from the type t of Time which is instantiated by an interpreter.
