Provides extension methods on all types to allow temporary, inspection/mutation (tapping) and transformation (piping)

Tapper

Provides extension methods on all types to allow temporary, inspection/mutation (tap), transformation (pipe), and safe type conversion without casting (conv).

Based on the Rust crate with a similar name tap.

Tap

The Tap extension allows you to perform an operation on an object and then return the original object. It's useful for debugging or performing side effects.

Example:

int number = 10;
number = number.tap((n) => ++n )
    .tap((n) => print("The number is ${n}"));
// Prints: The number is 10

Pipe

The Pipe extension lets you transform an object using a provided function and returns the transformed object.

Example:

int number = 10;
number = number.pipe((n) => ++n )
    .pipe((n) { 
      print("The number is ${n}"); 
      return n;
    });
// Prints: The number is 11

Conv

The Conv extension is used for type conversion. You can convert an object from one type to another, handling cases where the conversion is not possible.

Example:

String numericString = "123";
int? number = numericString.convInt(); // convInt exists for this type
// number is now 123

String nonNumericString = "abc";
Result<int, ConvException> result = nonNumericString.tryConv<int>();
// conversion is not possible and handled with Result

Valid Conversions

There also exists tryConv for dynamic inputs and concrete output.
