Struct fungui::Query

pub struct Query<'a, E: Extension + 'a> { /* private fields */ }

A query on a node that can be used to look up nodes in the same way that styles do.

The query! macro is a useful wrapper around this to match the syntax used in styles.

Implementations

impl<'a, E> Query<'a, E>where
    E: Extension + 'a,

pub fn into_owned(self) -> Query<'static, E>

Converts an empty query into an owned one

pub fn name<S>(self, name: S) -> Query<'a, E>where
    S: Into<Cow<'a, str>>,

Matches against the name of the current node if it is an element, fails otherwise.

pub fn text(self) -> Query<'a, E>

Matches against a text node otherwise it fails

pub fn property<S, V>(self, key: S, val: V) -> Query<'a, E>where
    V: AsValueRef<'a, E> + 'a,
    S: Into<Cow<'a, str>>,

Matches against a property on the current node compares the value. Fails if the property is missing or the value doesn’t match.

pub fn child(self) -> Query<'a, E>

Moves the matcher to a child node.

All other methods (name/text/property) will apply to the child after this

pub fn matches(self) -> QueryIterator<'a, E>

Returns a iterator over the possible matches

pub fn next(self) -> Option<Node<E>>

Returns a single match if any.

Alias for matches().next()
