Checked Functions
Functional interfaces that may throw checked exceptions.
Standard Function, BiFunction, Consumer and friends cannot throw checked exceptions without wrapping. functional-reactive ships drop-in replacements that can:
CheckedFunction<T, R>CheckedBiFunction<T1, T2, R>CheckedTriFunction<T1, T2, T3, R>CheckedConsumer<T>,CheckedSupplier<T>,CheckedPredicate<T>,CheckedExecutor
CheckedFunction<String, Integer> parse = Integer::parseInt;
Result<Integer> r = parse.apply("42"); // Success(42)
Result<Integer> r2 = parse.apply("oops"); // Failure("...")
Every checked function returns a Result, so failures travel through your pipeline without explicit try/catch.
