AsyncCompanion

de.rmgk.delay$.AsyncCompanion
trait AsyncCompanion[Ctx]

Companion object of Async, but with a type parameter to allow fine grained type inference. This could potentially be simplified if we ever get named type parameters.

Concrete methods

inline def apply[A](inline expr: Ctx ?=> A): Async[Ctx, A]

Main async syntax. The body expr is not executed until the returned Async is started with delay.extensions.run or one of the variants. Any exceptions raised in expr are forwarded to the handler of the async run.

inline def bind[Ctx, A](inline a: Async[Ctx, A]): A

While we don’t do bind inside of nested expressions, if the expression returns an async we can bind it. Sometimes, having this as a block is syntactically more convenient, i.e:

Attributes

inline def fromCallback[A](inline f: Ctx ?=> Callback[A] ?=> Unit): Async[Ctx, A]

Create a new Async from a callback. f is a block that may pass handler to a callback-based API.

inline def provided[Ctx, A](ctx: Ctx)(inline expr: Ctx ?=> A): Async[Any, A]

.provide, but you can put the context first.

inline def resource[R, A](inline open: R, inline close: R => Unit)(inline body: Ctx ?=> R => A): Async[Ctx, A]

Simple form of resource handling given an open and close function for some resource. Makes the resource available inside the async body and ensures it is closed as soon as body is done (exceptionally or normally).
