nidula 0.0.2

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

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) {}
