Children of a LookAheadSelection
.
Implementations§
source§impl<'a, S> LookAheadChildren<'a, S>
impl<'a, S> LookAheadChildren<'a, S>
sourcepub fn select(&self, name: &str) -> Option<LookAheadSelection<'a, S>>
pub fn select(&self, name: &str) -> Option<LookAheadSelection<'a, S>>
sourcepub fn has_child(&self, name: &str) -> bool
pub fn has_child(&self, name: &str) -> bool
Checks if the child selection with the specified name
exists.
If a child has an alias, it will only match if the alias matches the specified name
.
sourcepub fn names(&self) -> impl DoubleEndedIterator<Item = &'a str> + '_
pub fn names(&self) -> impl DoubleEndedIterator<Item = &'a str> + '_
Returns the possibly aliased names of the top-level children from the current selection.
sourcepub fn iter(
&self
) -> impl DoubleEndedIterator<Item = &LookAheadSelection<'a, S>> + '_
pub fn iter( &self ) -> impl DoubleEndedIterator<Item = &LookAheadSelection<'a, S>> + '_
Returns an Iterator
over these children, by reference.
