}

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

Variants

SG_NODE_KIND_DROP_SCOPES = 0

Removes everything from the current scope stack.

SG_NODE_KIND_JUMP_TO = 1

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 = 2

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 = 3

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 = 4

Pushes a scoped symbol onto the symbol stack.

SG_NODE_KIND_PUSH_SYMBOL = 5

Pushes a symbol onto the symbol stack.

SG_NODE_KIND_ROOT = 6

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

SG_NODE_KIND_SCOPE = 7

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