ValueTaskValueOption.either

Namespace: FsToolkit.ErrorHandling

Function Signature

Provide two functions to execute depending on the value of the voption. If the voption is ValueSome, the first function will be executed. If the voption is ValueNone, the second function will be executed.

(onValueSome : 'T -> ValueTask<'output>) 
	-> (onValueNone : unit -> ValueTask<'output>) 
	-> (input : ValueTask<'T voption>) 
	-> ValueTask<'output>

Examples

Example 1

ValueTaskValueOption.either (fun x -> valueTask { return x * 2 }) (fun () -> valueTask { return 0 }) (ValueTaskValueOption.valueSome 5)

// valueTask { 10 }

Example 2

ValueTaskValueOption.either (fun x -> valueTask { return x * 2 }) (fun () -> valueTask { return 0 }) (ValueTask<_>(ValueNone))

// valueTask { 0 }
