SwiftMapping.Contracts

Marker interfaces, attributes, and abstractions for SwiftMapping — the high-performance, source-generated, AOT-compatible object mapper for .NET.

When to use this package

Use SwiftMapping.Contracts in shared/contract libraries that define DTOs and mapping profiles but don't need the full mapping engine. This keeps your shared layer lightweight with zero transitive dependencies.
