libanvl.UUID

Immutable, endian-aware UUID library for .NET. Also generates Version V (5) and Version IV (4) UUIDs.

Requirements

.NET 6

Releases

• NuGet packages are available on NuGet.org
  • Embedded debug symbols
  • Source Link enabled
• NuGet packages from CI builds are available on the libanvl GitHub feed

Features

• Immutable
• Endian-aware
• Generates Version V (5) Namespaced UUIDs
• Generates Version IV (4) "Random" UUIDs
• Implicit conversion to and from System.Guid
  • Conversion to System.Guid always follows platform endianess
• Implicit conversion from byte[] and ReadOnlyMemory<byte>
• Copy to new byte[]
• Property access to all five UUID records
• No signed ints in the API
• Enumerable as a sequence of bytes
• More constructors than you can shake a stick at

Examples

public Guid GetWindowsTerminalNamespacedProfileGuid(string profileName)
{
    Guid terminalNamespace = new("2BDE4A90-D05F-401C-9492-E40884EAD1D8");
    return UUID.V(terminalNamespace, profileName);
}

public Guid GetWindowsTerminalNamespacedFragmentProfileGuid(string fragmentName, string profileName)
{
    Guid fragmentNamespace = new("f65ddb7e-706b-4499-8a50-40313caf510a");
    // Guid can be implicitly converted to UUID with endianess that matches the platform
    UUID fragmentUUID = UUID.V(fragmentNamespace, fragmentName);
    return UUID.V(fragmentUUID, profileName);
}

public UUID GetBigEndianUUID(UUID value)
{
    if (value.IsLittleEndian)
    {
        value = value.EndianSwap()
    }

    return value;
}
