Struct yrs::types::xml::XmlFragmentRef

#[repr(transparent)]
pub struct XmlFragmentRef(_);

A XML fragment, which works as an untagged collection of XML nodes.

Implementations

impl XmlFragmentRef

pub fn parent(&self) -> Option<XmlNode>

Trait Implementations

impl AsMut<Branch> for XmlFragmentRef

fn as_mut(&mut self) -> &mut Branch

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Branch> for XmlFragmentRef

fn as_ref(&self) -> &Branch

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for XmlFragmentRef

fn clone(&self) -> XmlFragmentRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for XmlFragmentRef

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

Formats the value using the given formatter.

impl From<BranchPtr> for XmlFragmentRef

fn from(inner: BranchPtr) -> Self

Converts to this type from the input type.

impl GetString for XmlFragmentRef

fn get_string<T: ReadTxn>(&self, txn: &T) -> String

Converts current XML node into a textual representation. This representation if flat, it doesn’t include any indentation.

impl IndexedSequence for XmlFragmentRef

fn sticky_index( &self, txn: &mut TransactionMut<'_>, index: u32, assoc: Assoc ) -> Option<StickyIndex>

Returns a StickyIndex equivalent to a human-readable index. Returns None if index is beyond the length of current sequence.

impl Into<XmlFragmentRef> for XmlElementRef

fn into(self) -> XmlFragmentRef

Converts this type into the (usually inferred) input type.

impl Observable for XmlFragmentRef

type Event = XmlEvent

fn try_observer( &self ) -> Option<&Observer<Arc<dyn Fn(&TransactionMut<'_>, &Self::Event)>>>

fn try_observer_mut( &mut self ) -> Option<&mut Observer<Arc<dyn Fn(&TransactionMut<'_>, &Self::Event)>>>

fn observe<F>( &mut self, f: F ) -> Subscription<Arc<dyn Fn(&TransactionMut<'_>, &Self::Event)>>where F: Fn(&TransactionMut<'_>, &Self::Event) + 'static,

Subscribes a given callback to be triggered whenever current y-type is changed. A callback is triggered whenever a transaction gets committed. This function does not trigger if changes have been observed by nested shared collections.

fn unobserve(&self, subscription_id: SubscriptionId)

Unsubscribes a previously subscribed event callback identified by given subscription_id.

impl PartialEq<XmlFragmentRef> for XmlFragmentRef

fn eq(&self, other: &XmlFragmentRef) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<BlockPtr> for XmlFragmentRef

type Error = BlockPtr

The type returned in the event of a conversion error.

fn try_from(value: BlockPtr) -> Result<Self, Self::Error>

Performs the conversion.

impl TryInto<XmlFragmentRef> for XmlNode

type Error = XmlNode

The type returned in the event of a conversion error.

fn try_into(self) -> Result<XmlFragmentRef, Self::Error>

Performs the conversion.

impl XmlFragment for XmlFragmentRef

fn first_child(&self) -> Option<XmlNode>

fn len<T: ReadTxn>(&self, txn: &T) -> u32

Returns a number of elements stored in current array.

fn insert<V>( &self, txn: &mut TransactionMut<'_>, index: u32, xml_node: V ) -> V::Returnwhere V: XmlPrelim,

Inserts a value at the given index. Inserting at index 0 is equivalent to prepending current array with given value, while inserting at array length is equivalent to appending that value at the end of it.

fn push_back<V>(&self, txn: &mut TransactionMut<'_>, xml_node: V) -> V::Returnwhere V: XmlPrelim,

Inserts given value at the end of the current array.

fn push_front<V>(&self, txn: &mut TransactionMut<'_>, xml_node: V) -> V::Returnwhere V: XmlPrelim,

Inserts given value at the beginning of the current array.

fn remove(&self, txn: &mut TransactionMut<'_>, index: u32)

Removes a single element at provided index.

fn remove_range(&self, txn: &mut TransactionMut<'_>, index: u32, len: u32)

Removes a range of elements from current array, starting at given index up until a particular number described by len has been deleted. This method panics in case when not all expected elements were removed (due to insufficient number of elements in an array) or index is outside of the bounds of an array.

fn get<T: ReadTxn>(&self, txn: &T, index: u32) -> Option<XmlNode>

Retrieves a value stored at a given index. Returns None when provided index was out of the range of a current array.

fn successors<'a, T: ReadTxn>(&'a self, txn: &'a T) -> TreeWalker<'a, &'a T, T>

Returns an iterator that can be used to traverse over the successors of a current XML element. This includes recursive step over children of its children. The recursive iteration is depth-first.
