Swift

static var pmkDefault: DispatchQueue


                    
                    
                    asDispatcher(group:qos:flags:)

Converts a DispatchQueue with given dispatching parameters into a Dispatcher

Declaration

Swift

func asDispatcher(group: DispatchGroup? = nil, qos: DispatchQoS? = nil, flags: DispatchWorkItemFlags? = nil) -> Dispatcher


                    
                    
                    async(_:group:qos:flags:execute:)

Asynchronously executes the provided closure on a dispatch queue, yielding a Guarantee.

DispatchQueue.global().async(.promise) {
    md5(input)
}.done { md5 in
    //…
}

_: Must be .promise to distinguish from standard DispatchQueue.async
group: A DispatchGroup, as for standard DispatchQueue.async
qos: A quality-of-service grade, as for standard DispatchQueue.async
flags: Work item flags, as for standard DispatchQueue.async
body: A closure that yields a value to resolve the guarantee.

Declaration

Swift

@available(macOS 10.10, iOS 2.0, tvOS 10.0, watchOS 2.0, *)
final func async<T>(_: PMKNamespacer, group: DispatchGroup? = nil, qos: DispatchQoS? = nil, flags: DispatchWorkItemFlags? = nil, execute body: @escaping () -> T) -> Guarantee<T>

Return Value

A new Guarantee resolved by the result of the provided closure.
