Struct ruby_prism_sys::pm_node

#[repr(C)]
pub struct pm_node {

}

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’s 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.

location: pm_location_t

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