Variants

Widget(SelectorWidget)

Match a widget

WidgetDirectChild(SelectorWidget)

Match a widget that is a direct child of the parent

WidgetDirectAfter(SelectorWidget)

Match a widget that follows directly after the previous widget

WidgetAfter(SelectorWidget)

Match a widget that follows after a previous widget

NthMod(usize, usize)

Match the nth child widget modulo a number

NthLastMod(usize, usize)

Match the nth child widget counted from the last child widget modulo a number

Nth(usize)

Match the nth child widget

NthLast(usize)

Match the nth child widget counted from the last child widget

OnlyChild

Match widgets that are the only child of their parent

Class(String)

Match widgets that have a class

State(StyleState<String>)

Match widgets that are in a state

Not(Box<Selector>)

Invert the nested selector

Implementations

impl Selector

pub fn match_sibling(&self, direct: bool, widget: &str) -> Option<bool>

Match a sibling widget of the current rule. If this selector is not a sibling selector None is returned.

pub fn match_child(&self, direct: bool, widget: &str) -> Option<bool>

Match a child widget of the current rule. If this selector is not a child selector None is returned.

pub fn match_meta<S: AsRef<str>>(
    &self,
    state: &[StyleState<S>],
    class: &str,
    n: usize,
    len: usize
) -> Option<bool>

Match parameters of the widget matched by the current rule. If this selector is not a meta selector None is returned.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Selector> for Selector

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
