Implementations§

source§

impl<T> PerOrigin<T>

source

pub fn borrow_for_origin(&self, origin: &Origin) -> &T

Returns a reference to the per-origin data for the specified origin.

source

pub fn borrow_mut_for_origin(&mut self, origin: &Origin) -> &mut T

source

pub fn iter_origins(&self) -> PerOriginIter<'_, T>

Iterates over references to per-origin extra style data, from highest level (author) to lowest (user agent).

source

pub fn iter_origins_rev(&self) -> PerOriginIter<'_, T>

source

pub fn iter_mut_origins(&mut self) -> PerOriginIterMut<'_, T>
