# rlvgl-widgets Options
`rlvgl-widgets` provides the built-in widget set that sits on top of
`rlvgl-core`.
## Default configuration
- Default features: none.
- Runtime model: `no_std` with `alloc`.
## Feature flags
This crate does not currently define any Cargo feature flags.
## What that means in practice
- Build behavior is stable across targets; there is no feature matrix to manage
in this crate itself.
- Code size and runtime cost are driven by which widgets you instantiate, not
by Cargo options.
- If you need codecs, simulator support, storage, or board integrations, those
switches live in `rlvgl-core`, `rlvgl-platform`, or the consuming app crate.
