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

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.

Instances

type GhcTime = Time UTCTime Day

Convenience alias for Time.

Interpreters

interpretTimeGhc :: Member (Embed IO) r => InterpreterFor GhcTime r

Interpret Time with the types from Time.

interpretTimeGhcAt :: Member (Embed IO) r => UTCTime -> InterpreterFor GhcTime r

Interpret Time with the types from Time, customizing the current time at the start of interpretation.

interpretTimeGhcConstant :: Member (Embed IO) r => UTCTime -> InterpreterFor GhcTime r

Interpret Time with the types from Time, customizing the current time to be constant.

interpretTimeGhcConstantNow :: Member (Embed IO) r => InterpreterFor GhcTime r

Interpret Time with the types from Time, customizing the current time to be constantly the time at the start of interpretation.

Combinators

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)

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.

while :: forall t d u r. Member (Time t d) r => TimeUnit u => u -> Sem r Bool -> Sem r ()

Repeatedly run the action, sleeping for interval between executions. Stops when action returns False.

loop :: forall t d u a r. Member (Time t d) r => TimeUnit u => u -> a -> (a -> Sem r a) -> Sem r ()

Repeatedly run the action, sleeping for interval between executions. The result of action is passed back to it for the next run, starting with initial.

loop_ :: forall t d u r. Member (Time t d) r => TimeUnit u => u -> Sem r () -> Sem r ()

Repeatedly run the action, sleeping for interval between executions.

diff :: forall dt u i1 i2. TimeUnit u => Torsor dt u => Instant i1 dt => Instant i2 dt => i1 -> i2 -> u

Subtract two arbitrary values that can be converted to an Instant.
