Struct CursorMut Copy item path

impl<M> CursorMut<'_, M>
where Link<M>: AnyFrameMeta,

pub fn move_next(&mut self)

Moves the cursor to the next frame towards the back.

If the cursor is pointing to the “ghost” non-element then this will move it to the first element of the LinkedList. If it is pointing to the last element of the LinkedList then this will move it to the “ghost” non-element.

pub fn move_prev(&mut self)

Moves the cursor to the previous frame towards the front.

If the cursor is pointing to the “ghost” non-element then this will move it to the last element of the LinkedList. If it is pointing to the first element of the LinkedList then this will move it to the “ghost” non-element.

pub fn current_meta(&mut self) -> Option<&mut M>

Gets the mutable reference to the current frame’s metadata.

pub fn take_current(&mut self) -> Option<UniqueFrame<Link<M>>>

Takes the current pointing frame out of the linked list.

If successful, the frame is returned and the cursor is moved to the next frame. If the cursor is pointing to the back of the list then it is moved to the “ghost” non-element.

pub fn insert_before(&mut self, frame: UniqueFrame<Link<M>>)

Inserts a frame before the current frame.

If the cursor is pointing at the “ghost” non-element then the new element is inserted at the back of the LinkedList.

pub fn as_list(&self) -> &LinkedList<M>

Provides a reference to the linked list.
