## Data Fields
pm_node_type_t | type
| This represents the type of the node.
pm_node_flags_t | flags
| This represents any flags on the node.
uint32_t | node_id
| The unique identifier for this node, which is deterministic based on the source.
pm_location_t | location
| This is the location of the node in the source.

## Detailed Description

This is the base structure that represents a node in the syntax tree.

It is embedded into every node type.

Definition at line 1068 of file ast.h.

## Field Documentation

## ◆ flags

pm_node_flags_t pm_node::flags

This represents any flags on the node.

Some are common to all nodes, and some are specific to the type of node.

Definition at line 1079 of file ast.h.

## ◆ location

pm_location_t pm_node::location

This is the location of the node in the source.

It's a range of bytes containing a start and an end.

Definition at line 1091 of file ast.h.

Referenced by pm_dump_json().

## ◆ node_id

uint32_t pm_node::node_id

The unique identifier for this node, which is deterministic based on the source.

It is used to identify unique nodes across parses.

Definition at line 1085 of file ast.h.

## ◆ type

pm_node_type_t pm_node::type

This represents the type of the node.

It somewhat maps to the nodes that existed in the original grammar and ripper, but it's not a 1:1 mapping.
