Struct HandleManager 

pub struct HandleManager { /* private fields */ }

Handle manager for a node

Implementations

impl HandleManager

pub fn new(node_id: NodeId) -> Self

Create a new handle manager

pub fn add_handle(&mut self, handle: Handle) -> Result<()>

Add a handle

pub fn remove_handle(&mut self, handle_id: &HandleId) -> Result<Handle>

Remove a handle

pub fn get_handle(&self, handle_id: &HandleId) -> Option<&Handle>

Get a handle by ID

pub fn handles(&self) -> &[Handle]

Get all handles

pub fn handle_at_position( &self, point: Position, node_pos: Position, node_size: Size, handle_size: f64, ) -> Option<&Handle>

Find handle at position

pub fn source_handles(&self) -> impl Iterator<Item = &Handle>

Get source handles

pub fn target_handles(&self) -> impl Iterator<Item = &Handle>

Get target handles

pub fn connection_count(&self, _handle_id: &HandleId) -> usize

Count connections for a handle

Note: This method requires graph integration to work properly. Use Graph::get_handle_connections() directly for accurate counting.

pub fn can_accept_connection(&self, handle_id: &HandleId) -> bool

Check if handle can accept new connections

Note: This method requires graph integration to work properly. Use Graph::can_handle_accept_connection() for accurate validation.

Trait Implementations

impl Clone for HandleManager

fn clone(&self) -> HandleManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandleManager

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

Formats the value using the given formatter.

impl Default for HandleManager

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for HandleManager

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

Tests for self and other values to be equal, and is used by ==.

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

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