Enum MonitorQuery 

pub enum MonitorQuery {
    ParentOrPrimary,
    Primary,
    Query(Arc<dyn Fn() -> Option<MonitorInfo> + Sync + Send>),
}

A selector that returns a MonitorInfo.

Variants

ParentOrPrimary

The parent window monitor, or Primary if the window has no parent.

Note that the window is not moved automatically if the parent window is moved to another monitor, only after the query variable updates.

This is the default value.

Primary

The primary monitor, if there is any monitor.

Query(Arc<dyn Fn() -> Option<MonitorInfo> + Sync + Send>)

Custom query closure.

If the closure returns None the ParentOrPrimary query is used, if there is any.

You can use the MONITORS service in the query closure to select a monitor.

Implementations

impl MonitorQuery

pub fn new( query: impl Fn() -> Option<MonitorInfo> + Send + Sync + 'static, ) -> MonitorQuery

New query.

pub fn select(&self) -> Option<MonitorInfo>

Runs the query.

pub fn select_fallback(&self) -> MonitorInfo

Runs the query. Falls back to Primary, or the largest or MonitorInfo::fallback.

Trait Implementations

impl Clone for MonitorQuery

fn clone(&self) -> MonitorQuery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MonitorQuery

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for MonitorQuery

fn default() -> MonitorQuery

Returns the “default value” for a type.

impl PartialEq for MonitorQuery

fn eq(&self, other: &MonitorQuery) -> bool

Returns true only if both are MonitorQuery::Primary.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
