Struct Selectors 

pub struct Selectors;

Functions for building Selectors.

Every function takes the selector that precedes the new one (None to start a selector). The same functions are available as chaining methods on Selector:

// Button.big > :is(Control)
let selector = Selectors::of_type::<Button>().class("big").child().is::<Control>();

Returns a selector which matches a type or a derived type.

pub fn is<T: ObjectType + Upcast<StyledElement>>() -> Selector

Returns a selector which matches class T or a class derived from it.

pub fn name(previous: Option<Selector>, name: &str) -> Selector

Returns a selector which matches a control’s name.

pub fn nesting(_previous: Option<Selector>) -> Selector

Returns the nesting selector, which stands for the selector of the parent style.

pub fn not(previous: Option<Selector>, argument: Selector) -> Selector

Returns a selector which inverts the results of selector argument.

pub fn not_with( previous: Option<Selector>, argument: impl FnOnce(Option<Selector>) -> Selector, ) -> Selector

Returns a selector which inverts the results of the selector built by argument.

pub fn nth_child(previous: Option<Selector>, step: i32, offset: i32) -> Selector

Returns a selector which matches elements based on their position among a group of siblings.

pub fn nth_last_child( previous: Option<Selector>, step: i32, offset: i32, ) -> Selector

Returns a selector which matches elements based on their position among a group of siblings, counting from the end.

pub fn of_type_info( previous: Option<Selector>, type_: &'static TypeInfo, ) -> Selector

Returns a selector which matches a type.

pub fn of_type<T: ObjectType + Upcast<StyledElement>>() -> Selector

Returns a selector which matches class T exactly.

pub fn or(selectors: impl IntoIterator<Item = Selector>) -> Selector

Returns a selector which ORs selectors.

pub fn property_equals<T: PropertyValue>( previous: Option<Selector>, property: &'static StyledProperty<T>, value: T, ) -> Selector

Returns a selector which matches a control with the specified property value.

pub fn property_equals_untyped( previous: Option<Selector>, property: &'static FerroProperty, value: BoxedValue, ) -> Selector
