Struct style::selector_parser::PerPseudoElementMap

pub struct PerPseudoElementMap<T> { /* fields omitted */ }

A per-pseudo map, from a given pseudo to a T.

Methods

impl<T> PerPseudoElementMap<T>

pub fn get(&self, pseudo: &PseudoElement) -> Option<&T>

Get an entry in the map.

pub fn clear(&mut self)

Clear this enumerated array.

pub fn set(&mut self, pseudo: &PseudoElement, value: T)
