The different kinds of node that can appear in a stack graph.

Variants

SG_NODE_KIND_DROP_SCOPES

Removes everything from the current scope stack.

SG_NODE_KIND_EXPORTED_SCOPE

A node that can be referred to on the scope stack, which allows “jump to” nodes in any other part of the graph can jump back here.

SG_NODE_KIND_INTERNAL_SCOPE

A node internal to a single file. This node has no effect on the symbol or scope stacks; it’s just used to add structure to the graph.

SG_NODE_KIND_JUMP_TO

The singleton “jump to” node, which allows a name binding path to jump back to another part of the graph.

SG_NODE_KIND_POP_SCOPED_SYMBOL

Pops a scoped symbol from the symbol stack. If the top of the symbol stack doesn’t match the requested symbol, or if the top of the symbol stack doesn’t have an attached scope list, then the path is not allowed to enter this node.

SG_NODE_KIND_POP_SYMBOL

Pops a symbol from the symbol stack. If the top of the symbol stack doesn’t match the requested symbol, then the path is not allowed to enter this node.

SG_NODE_KIND_PUSH_SCOPED_SYMBOL

Pushes a scoped symbol onto the symbol stack.

SG_NODE_KIND_PUSH_SYMBOL

Pushes a symbol onto the symbol stack.

SG_NODE_KIND_ROOT

The singleton root node, which allows a name binding path to cross between files.
