Enum penrose::core::ring::Selector

pub enum Selector<'a, T> {
    Any,
    Focused,
    Index(usize),
    WinId(WinId),
    Condition(&'a dyn Fn(&T) -> bool),
}

Used with WindowManager helper functions to select an element from the known workspaces or clients.

For functions returning a single elemt this is equivalent to Focused, for functions returning multiple elements this will return the entire collection.

Index(usize)

The element at this index.

WinId(WinId)

The element with/containing this client ID.

Condition(&'a dyn Fn(&T) -> bool)
