Metadata

A lightweight Dart library for Rust-like Option/Result types. Supports exhaustive pattern matching and compile-time safe, chainable None/Err propagation.

0.1.0 #

  • Renamed most classes and methods and static methods. Names are longer, but much more obvious:
    • prop was renamed to unwrapOrPropagateErr and unwrapOrPropagateNone.
    • catchProp/catchPropAsync were renamed to syncErrPropagationScope/asyncErrPropagationScope and syncNonePropagationScope/asyncNonePropagationScope.
    • ResultPropError was renamed to ErrPropagation. Same for OptionPropError, which was renamed to NonePropagation.
    • ResultPropToken was renamed to ErrPropagationToken. Same for OptionPropToken, which was renamed to NonePropagationToken.
  • Added Propagation abstract class.
  • Improved and refactored tests.
  • Improved docstring.
  • Improved README.

0.0.3 #

  • Add try-catch warning to README.
  • Add more code to nidula_example.dart.
  • Small fix to example in README.

0.0.2 #

  • Upload again to fix repository URL detection.

0.0.1 #

  • Initial version.
    • Forked from option_result, bringing the following enhancements:
      • Try-operator implementation rewritten from scratch.
        • Compile time safety through propagation tokens.
        • Chainable.
        • Simpler and clearer library-internal error handling strategy.
      • T and E types must extend Object (thus, non-null values are prohibited).
        • This enforces composition with Option types (Option<T>) instead of nullable types (T?).
      • Only T v and E e fields (and, thus, getters) are available.
        • value, val, err and error aliases were removed.
      • There is only a single public library to import components from.
      • Final modifiers to prevent extending Ok, Err, Some and None.
      • == operator takes all generic types into consideration when comparing Option objects and Result objects.
      • Added variable names to all function parameters in types
        • Callback autocomplete outputs e.g. (v) {} instead of (p0) {}
