ofCatchTask

Namespace: FsToolkit.ErrorHandling

Transforms a Task<'T> into a Task<Result<'T, exn>>, catching any exceptions thrown by the task and wrapping them in the Error case.

Unlike ofTask, this function catches exceptions that escape from the task and maps them to Error. If the task completes successfully, the result is wrapped in Ok.

Function Signature

Task<'T> -> Task<Result<'T, exn>>

Examples

Example 1

let result = TaskResult.ofCatchTask (task { return 42 })
// task { return Ok 42 }

Example 2

let result = TaskResult.ofCatchTask (task { failwith "something went wrong" })
// task { return Error (System.Exception("something went wrong")) }
