Module render_tree 

This module provides functionality for rendering an execution plan as a tree structure. It helps in visualizing how different operations in a query are connected and organized.

Structs

Coordinate

Represents a 2D coordinate in the rendered tree. Used to track positions of nodes and their connections.

RenderTree

Main structure for rendering an execution plan as a tree. Manages a 2D grid of nodes and their layout information.

RenderTreeNode

Represents a node in the render tree, containing information about an execution plan operator and its relationships to other operators.

Functions

create_tree_recursive 🔒

Recursively builds the render tree structure. Traverses the execution plan and creates corresponding render nodes while maintaining proper positioning and parent-child relationships.

fmt_display 🔒

get_tree_width_height 🔒

Calculates the required dimensions of the tree. This ensures we allocate enough space for the entire tree structure.
