menu_context.rs

1//! Menu context computation.
2//!
3//! This module provides methods to compute menu context values that determine
4//! when menu items and commands should be enabled or disabled. Each context
5//! value has a dedicated method that encapsulates the logic for checking
6//! whether that feature is available.
