NextGenSoftware.ErrorHandling

Structured error handling and the OASISResult pattern — the error propagation backbone of the OASIS Omniverse ecosystem (HoloNET, the OASIS API, STAR ODK, OurWorld).

NuGet License: MIT .NET

Part of the OASIS Omniverse v2.0 Reboot. Visit oasisomniverse.one.

Features

  • OASISResult<T> — null-safe async result type; return success or failure without throwing across API boundaries
  • OASISResult (non-generic) for void operations
  • Structured exception wrappers with rich context metadata
  • Consistent error propagation across all 85+ OASIS API packages and HoloNET
  • Integrates with NextGenSoftware.Logging
  • Multi-target: .NET 8, .NET 9, .NET 10

Installation

dotnet add package NextGenSoftware.ErrorHandling

Quick Start

using NextGenSoftware.ErrorHandling;

public async Task<OASISResult<MyData>> LoadDataAsync(string id)
{
    var result = new OASISResult<MyData>();
    try
    {
        result.Result = await _db.GetAsync(id);
    }
    catch (Exception ex)
    {
        result.Exception = ex;
        result.Message   = $"Failed to load {id}.";
        result.IsError   = true;
    }
    return result;
}

// Call site
var result = await myService.LoadDataAsync("abc123");
if (result.IsError)
    Console.WriteLine($"Error: {result.Message}");
else
    Process(result.Result);

OASISResult Properties

Property Type Description
Result T The returned value on success
IsError bool true if the operation failed
IsWarning bool true if a non-fatal warning occurred
Message string Human-readable error/success message
Exception Exception Underlying exception if any
InnerMessages List<string> Accumulated sub-messages from nested calls
