  • reuse default exceptions for Result<T> and ErrorState
  • add span fast path to many OptionLinqExtensions
  • updated TUnit to 1.56.18

  • add OrThrow(arg, messageSupplier)
  • add ErrorState{<E>}.ToResult(Func<Result<T{, E}>>)
  • add ErrorState{<E>}.ToResultAsync(Func<Task<Result<T{, E}>>>)
  • make TryIndexOf and TryLastIndexOf generic

0.3.0

  • improved Option joining (#37)
    • Join API for Option<T>, Result<T> and Result<T, E> up to 4 elements (after that it starts nesting)
    • Result/ErrorState.CombineErrors API

  • improved LINQ integration (#32)
    • WhereSuccess
    • WhereError
    • Branch for sequences of Result<T> and Result<T, E>

    • ValuesOrError for sequences of Option<T>
    • rename IEnumerable<T>.FirstOrError to TryFirst

  • (TUnit) IsSuccess(condition) for Option<T> Result<T> and Result<T, E>
  • (TUnit) IsError(condition) for Result<T>, Result<T, E>, ErrorState and ErrorState<E>
