Struct PrepareIndexCloningNode 

pub struct PrepareIndexCloningNode<T> {
    pub pos_array: Vec<(bool, usize)>,
    /* private fields */
}

Preparation node - built once, stores the reference structure. Uses HashMap to detect shared references.

Fields

pos_array: Vec<(bool, usize)>

(is_existing, position) for each reference in traversal order

Implementations

impl<T> PrepareIndexCloningNode<T>

pub fn new() -> Self

pub fn with_capacity(capacity: usize) -> Self

pub fn handle_reference(&mut self, r: &IndexRef<T>)

Handle a reference during preparation phase. Records whether it’s new or existing, and its position.

pub fn unique_count(&self) -> usize

Get the number of unique references.

Trait Implementations

impl<T> Default for PrepareIndexCloningNode<T>

fn default() -> Self

Returns the “default value” for a type.
