Module connection 

Renderer-neutral connection gesture helpers.

Adapters own pointer capture and platform hit testing. The runtime owns deterministic connection activation and handle proximity policy that should feel like XyFlow across renderers.

Structs

ClosestConnectionHandle

Closest handle resolution result.

ClosestConnectionHandleInput

Input for resolving the closest connection handle near a pointer.

ConnectEdgeRequest

Rules-driven request for connecting two existing ports.

ConnectionDragActivationInput

Screen-space input for deciding whether a connection drag should activate.

ConnectionHandleCandidate

Renderer-normalized handle geometry in canvas coordinates.

ConnectionHandleConnection

XyFlow-shaped connection endpoints resolved from a start handle and target handle.

ConnectionHandleIndicator

XyFlow-style per-handle interaction indicator state.

ConnectionHandleIndicatorInput

Input for resolving XyFlow-style handle interaction indicator state.

ConnectionHandleRef

Stable identity for a renderer handle participating in a connection gesture.

ConnectionTargetCandidate

Renderer-normalized target-handle geometry plus target connectability policy.

ConnectionTargetFromHandlesInput

Input for resolving the current connection target from renderer-normalized handle candidates.

ConnectionTargetHandle

Candidate target handle plus adapter-resolved connectability policy.

ConnectionTargetInput

Input for resolving whether a target handle can complete a connection gesture.

ReconnectEdgeRequest

Rules-driven request for reconnecting one endpoint of an existing edge.

ResolvedConnectionTarget

Resolved target semantics for connection feedback and completion callbacks.

Enums

ConnectEdgeError

Error returned when a connect request could not be committed.

ConnectionHandleValidity

XyFlow-compatible validity state for a connection target candidate.

ReconnectEdgeError

Error returned when a reconnect request could not be committed.

Constants

CONNECT_EDGE_TRANSACTION_LABEL

Default transaction label used for committed connect updates.

RECONNECT_EDGE_TRANSACTION_LABEL

Default transaction label used for committed reconnect updates.

Functions

closest_connection_handle

Returns the nearest handle inside connection_radius, matching XyFlow tie semantics.

connect_edge_transaction

connect_edge_transaction_with_edge_id

connection_drag_threshold_met

Returns whether pointer movement should start a connection drag.

connection_handle_validity

Resolves XyFlow’s true | false | null connection feedback into a Rust enum.

reconnect_edge_transaction

resolve_connection_handle_indicator

Resolves the handle booleans used by XyFlow’s Handle component.

resolve_connection_target

Resolves XyFlow handle target semantics without depending on DOM hit testing.

resolve_connection_target_from_handles

Resolves connection target feedback from renderer-normalized handle geometry and policies.
