You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: switch.rs
    path of file: ./repos/kanata/keyberon/src/action
    
    the code of the file until where you have to start completion: //! Handle processing of the switch action for Keyberon.
//!
//! Limitations:
//! - Maximum opcode length: 4095
//! - Maximum boolean expression depth: 8
//! - Maximum key recency: 7, where 0 is the most recent key press
//!
//! The intended use is to build up a `Switch` struct and use that in the `Layout`.
//!
//! The `Layout` will use `Switch::actions` to iterate over the actions that should be activated
//! when the corresponding key is pressed.
