```csharp
public static void WriteField<TBufferWriter>(ref Writer<TBufferWriter> writer, uint fieldIdDelta, ReadOnlyMemory<byte> value)
```

Writes a field without type info (expected type is statically known).

### Parameters

- `writer` (`Writer<TBufferWriter>`): The writer.
- `fieldIdDelta` (`uint`): The field identifier delta.
- `value` (`ReadOnlyMemory<byte>`): The value.
