Struct content_tree::MutCursor

#[repr(transparent)]
pub struct MutCursor<'a, E: ContentTraits, I: TreeIndex<E>, const IE: usize, const LE: usize> {
    pub inner: UnsafeCursor<E, I, IE, LE>,
    // some fields omitted
}

A mutable cursor into a ContentTree. Mutable cursors inherit all the functionality of Cursor, and can also be used to modify the content tree.

A mutable cursor mutably borrows the content tree. Only one mutable cursor can exist at a time.

Fields

inner: UnsafeCursor<E, I, IE, LE>
