Enum Selector 

pub enum Selector {
    Type(String),
    Class(String),
    Id(String),
    Universal,
    PseudoClass(PseudoClass),
    Descendant(Box<Selector>, Box<Selector>),
    Child(Box<Selector>, Box<Selector>),
    Compound(Vec<Selector>),
}

TCSS selector — a single selector or combinator expression.

Variants

Type(String)

Matches widgets by type name, e.g. Button

Class(String)

Matches widgets with a CSS class, e.g. .active

Id(String)

Matches widgets with a specific ID, e.g. #sidebar

Universal

Matches any widget (*)

PseudoClass(PseudoClass)

Matches widgets with a given pseudo-class, e.g. :focus

Descendant(Box<Selector>, Box<Selector>)

Matches a widget that is any descendant of the left selector, e.g. Screen Button

Child(Box<Selector>, Box<Selector>)

Matches a widget that is a direct child of the left selector, e.g. Container > Button

Compound(Vec<Selector>)

Multiple simple selectors that all apply to the same element, e.g. Button.active:focus

Implementations

impl Selector

pub fn specificity(&self) -> Specificity

Calculate specificity for this selector.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selector

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

Formats the value using the given formatter.

impl PartialEq for Selector

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

Tests for self and other values to be equal, and is used by ==.

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

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