Assembly: Falco.UnionRoutes.dll
Parent Module: Extraction

 let slugParser: Parser<Slug> = fun s -> Ok (Slug s)
 let intParser: Parser<int> = fun s ->
     match Int32.TryParse s with
     | true, i -> Ok i
     | _ -> Error "Invalid integer"

val slugParser: s: 'a -> Result<'b,'c>

val s: 'a

union case Result.Ok: ResultValue: 'T -> Result<'T,'TError>

val intParser: s: 'a -> Result<'b,string>

Multiple items
val int: value: 'T -> int (requires member op_Explicit)

--------------------
type int = int32

--------------------
type int<'Measure> = int

val i: 'b

union case Result.Error: ErrorValue: 'TError -> Result<'T,'TError>
