Enum penrose::Selector

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

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

Variants

Any

Any element in the target collection.

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

Focused

The focused element of the target collection.

Index(usize)

Tuple Fields

0: usize

The element at this index.

WinId(Xid)

Tuple Fields

0: Xid

The element with/containing this client ID.

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

Tuple Fields

0: &'a dyn Fn(&T) -> bool

The first element satisfying this condition.
