High-performance JSON for .NET

// 1. Annotate a partial struct
[JsonSchemaTypeGenerator("Schemas/person.json")]
public readonly partial struct Person;

// 2. Parse JSON — pooled memory, zero-copy
using var doc = ParsedJsonDocument<Person>.Parse(
    """{"name":"Alice","age":30}""");
Person person = doc.RootElement;

// 3. Access typed properties
string name = (string)person.Name;   // "Alice"
int age = (int)person.Age;           // 30

// 4. Validate against the schema
bool valid = person.EvaluateSchema(); // true

// 5. Mutate with the builder pattern
using var ws = JsonWorkspace.Create();
using var b = person.CreateBuilder(ws);
Person.Mutable root = b.RootElement;
root.SetAge(31);
// {"name":"Alice","age":31}
