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) {}
