traverseTaskResultA

List.traverseTaskResultA

Namespace: FsToolkit.ErrorHandling

Function Signature:

('a -> Task<Result<'b,'c>>) -> 'a list -> Task<Result<'b list, 'c list>>

Note that traverse is the same as map >> sequence. See also List.sequenceTaskResultA.

This is applicative, collecting all errors.

This is the same as traverseResultA except that it uses Task<Result<_,_>> instead of Result<_,_>.
