Struct pm_node 

#[repr(C)]
pub struct pm_node {
    pub type_: pm_node_type_t,
    pub flags: pm_node_flags_t,
    pub node_id: u32,
    pub location: pm_location_t,
}

This is the base structure that represents a node in the syntax tree. It is embedded into every node type.

Fields

type_: pm_node_type_t

This represents the type of the node. It somewhat maps to the nodes that existed in the original grammar and ripper, but it is not a 1:1 mapping.

flags: pm_node_flags_t

This represents any flags on the node. Some are common to all nodes, and some are specific to the type of node.

node_id: u32

The unique identifier for this node, which is deterministic based on the source. It is used to identify unique nodes across parses. Nodes created outside of parsing have no position in the source and can use 0, which no parsed node uses.

location: pm_location_t

This is the location of the node in the source. It is a range of bytes containing a start and an end.
