Construct a target from low-level runner callbacks.
run returns zero for a kept input and a non-zero status for a rejected
input. Failures should use crash or expect rather than status codes.
Target
:= [Target({ name : Str, run : List(U8) -> U8, show : List(U8) -> Str })]Advanced, type-erased bridge between a typed Roc property and the native runner.
Applications normally construct this value with Fuzz.target or
Fuzz.target_with and expose it as target. The methods here define the
small byte-oriented ABI consumed by the embedded runner.
Return the human-readable target name reported by the executable.
Decode and test one raw input, returning the runner status code.
Decode one raw input into a human-readable typed value.
