Struct style::selector_parser::PerPseudoElementMap

pub struct PerPseudoElementMap<T> {
    entries: [Option<T>; 19],
}

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

Fields

entries: [Option<T>; 19]

Implementations

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)

Set an entry value.

Returns an error if the element is not a simple pseudo.

pub fn get_or_insert_with<F>(&mut self, pseudo: &PseudoElement, f: F) -> &mut T

where F: FnOnce() -> T,

Get an entry for pseudo, or create it with calling f.

pub fn iter(&self) -> Iter<'_, Option<T>>

Get an iterator for the entries.

pub fn iter_mut(&mut self) -> IterMut<'_, Option<T>>

Get a mutable iterator for the entries.

Trait Implementations

impl<T: Clone> Clone for PerPseudoElementMap<T>

fn clone(&self) -> PerPseudoElementMap<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for PerPseudoElementMap<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for PerPseudoElementMap<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> MallocSizeOf for PerPseudoElementMap<T>

where T: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
