# Types & errors _Arguments, results, and errors_ Every public type is re-exported at the crate root: import from `medius::`, not `medius::types::`. The argument [enums](/library/types/enums.md), the [structs](/library/types/structs.md) the box reports back, the low-level [frame types](/library/types/frames.md), and the one [`Error`](/library/types/errors.md) all live here. #### EXAMPLE ```rust use medius::{Button, Action, Health, Version, Error, Result}; // One flat namespace. This does NOT work: // use medius::types::Button; ``` ## Reference pages _Pick a group_ - [Enums](/library/types/enums.md): Button, Action, RebootTarget, LogLevel, CatchEvent - [Structs](/library/types/structs.md): Version, Health, MouseCaps, KbdCaps, Key, MediaKey, and more - [Frames](/library/types/frames.md): FrameType, DecodedFrame - [Errors](/library/types/errors.md): Error, Result
