Struct UseMediaQuery 

pub struct UseMediaQuery {
    pub matches: Signal<bool>,
    pub query: &'static str,
    /* private fields */
}

Reactive state for one CSS media query.

The handle carries the query it watches, the current match result, and the teardown that removes the change listener from the browser’s MediaQueryList.

The match result is a Signal<bool>: a render closure that reads it re-renders when the query starts or stops matching, and nothing else in the tree is disturbed.

Fields

matches: Signal<bool>

Whether the query currently matches.

query: &'static str

The media query text this handle watches.
