Variants§

Append

Fields

§prev: &'a Node

§

Insert

Fields

§prev: &'a Node
§added: &'a [&'a Node]
§next: &'a Node
§

Prepend

Fields

§added: &'a [&'a Node]
§next: &'a Node
§

Replace

Fields

§prev: Option<&'a Node>
§removed: &'a Node
§added: &'a [&'a Node]
§next: Option<&'a Node>
§

ReplaceAll

Fields

§removed: &'a [&'a Node]
§added: &'a [&'a Node]
§

ChangeText

Mutation for when a Text node’s data is modified. This doesn’t change the structure of the list, which is what the other variants’ fields are stored for at the moment, so this can just have no fields.

Implementations§

source§

impl<'a> ChildrenMutation<'a>

source

fn insert( prev: Option<&'a Node>, added: &'a [&'a Node], next: Option<&'a Node> ) -> ChildrenMutation<'a>

source

fn replace( prev: Option<&'a Node>, removed: &'a Option<&'a Node>, added: &'a [&'a Node], next: Option<&'a Node> ) -> ChildrenMutation<'a>

source

fn replace_all( removed: &'a [&'a Node], added: &'a [&'a Node] ) -> ChildrenMutation<'a>

source

pub fn next_child(&self) -> Option<&Node>

Get the child that follows the added or removed children. Currently only used when this mutation might force us to restyle later children (see HAS_SLOW_SELECTOR_LATER_SIBLINGS and Element’s implementation of VirtualMethods::children_changed).

source

pub fn modified_edge_element(&self) -> Option<Root<Dom<Node>>>

If nodes were added or removed at the start or end of a container, return any previously-existing child whose “:first-child” or “:last-child” status may have changed.

NOTE: This does not check whether the inserted/removed nodes were elements, so in some cases it will return a false positive. This doesn’t matter for correctness, because at worst the returned element will be restyled unnecessarily.
