Struct UseMutationObserverOptions

pub struct UseMutationObserverOptions { /* private fields */ }

Options for use_mutation_observer_with_options.

Implementations

impl UseMutationObserverOptions

pub fn subtree(self, value: bool) -> Self

Set to true to extend monitoring to the entire subtree of nodes rooted at target. All of the other properties are then extended to all of the nodes in the subtree instead of applying solely to the target node. The default value is false.

pub fn child_list(self, value: bool) -> Self

Set to true to monitor the target node (and, if subtree is true, its descendants) for the addition of new child nodes or removal of existing child nodes. The default value is false.

pub fn attributes(self, value: bool) -> Self

Set to true to watch for changes to the value of attributes on the node or nodes being monitored. The default value is true if either of attribute_filter or attribute_old_value is specified, otherwise the default value is false.

pub fn attribute_filter<OptionInnerType>( self, value: impl Into<Option<OptionInnerType>>, ) -> Self

where OptionInnerType: Into<Vec<String>>,

An array of specific attribute names to be monitored. If this property isn’t included, changes to all attributes cause mutation notifications.

pub fn attribute_old_value(self, value: bool) -> Self

Set to true to record the previous value of any attribute that changes when monitoring the node or nodes for attribute changes; See Monitoring attribute values for an example of watching for attribute changes and recording values. The default value is false.

pub fn character_data<OptionInnerType>( self, value: impl Into<Option<OptionInnerType>>, ) -> Self

where OptionInnerType: Into<bool>,

Set to true to monitor the specified target node (and, if subtree is true, its descendants) for changes to the character data contained within the node or nodes. The default value is true if character_data_old_value is specified, otherwise the default value is false.

pub fn character_data_old_value(self, value: bool) -> Self

Set to true to record the previous value of a node’s text whenever the text changes on nodes being monitored. The default value is false.
