Implementations

impl Handle

pub fn new( id: impl Into<HandleId>, handle_type: HandleType, position: HandlePosition, ) -> Self

Create a new handle

pub fn source(id: impl Into<HandleId>, position: HandlePosition) -> Self

Create a source handle

pub fn target(id: impl Into<HandleId>, position: HandlePosition) -> Self

Create a target handle

pub fn with_connection_limit(self, limit: usize) -> Self

Set connection limit

pub fn with_connection_types(self, types: Vec<String>) -> Self

Set valid connection types

pub fn with_style(self, style: impl Into<String>) -> Self

Set style

pub fn absolute_position(&self, node_pos: Position, node_size: Size) -> Position

Calculate absolute position of handle given node position and size

pub fn contains_point( &self, point: Position, node_pos: Position, node_size: Size, handle_size: f64, ) -> bool

Check if a point is within the handle’s bounds

pub fn can_connect_to(&self, other: &Handle) -> bool

Check if this handle can connect to another handle

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl PartialEq for Handle

fn eq(&self, other: &Handle) -> 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.
