Std.Graph.addEdge

fn

This is a callable function.

What it does

The graph with an edge from one node to another.

Both ends are added as nodes. An edge to a node the caller never mentioned

is still a statement that the node exists, and requiring it to be declared

first would only make callers write it twice.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
