Function field

field<T extends TSchema>(fieldId: number, schema: T): TStructField<T>
Tags a schema with a field ID for struct serialization.

Field IDs must be unique within a struct and in range 0-127 (bit 7 clear). Encoder sorts fields by ascending ID; decoder validates this order.
Type Parameters

Parameters
- fieldId: number
  Field identifier (0-127)

Example

const nameField = field(0, RString());
const ageField = field(1, RU8());
```
