Metano Runtime

Runtime support library for code generated by the Metano C# → TypeScript transpiler (v1.0.3, updated April 2026). Provides C#-compatible primitives such as HashCode (xxHash32), HashSet with structural equality, a full LINQ API via Enumerable, a branded UUID type for System.Guid mapping, runtime type guards (isInt32, isString, etc.), and JSON serialization (system/json). Release cadence is active (multiple versions per month). Key differentiator: automatically added by Metano to generated projects; side-effect-free for tree-shaking. Requires @typescript/native-preview (peer dep). Only relevant for Metano users; not designed for general-purpose use.
