Struct Node

pub struct Node { /* private fields */ }

A file stack node.

Historically, RGBDS stored locations as simple strings, which were extended to contain the the full “file stack” (included files, macro calls, etc.); however, object files grew very large, as the strings contained a lot of repetition.

To solve the bloat problem, file stack nodes were introduced in format v9 r5; they store each scope in a unique way, building a tree. However, scopes don’t store line numbers, since several definitions may occur per scope, but instead store the line number at which their parent scope was exited.

Implementations

impl Node

pub fn parent(&self) -> Option<(u32, u32)>

Returns the ID of the parent node, and the line number at which it was exited. If the node is a root node, None is returned instead.

pub fn type_data(&self) -> &NodeType

The node’s type and associated data.

Trait Implementations

impl Debug for Node

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
