Struct NodeIndex 

pub struct NodeIndex { /* private fields */ }

Top-level index organizing all variable nodes in a BIDS dataset.

The NodeIndex maintains a flat list of nodes (both run-level and higher-level) and provides methods to find, create, and query nodes by level and entity values. Nodes are created during variable loading and can be queried to extract variable collections for statistical modeling.

Implementations

impl NodeIndex

pub fn new() -> Self

pub fn create_run_node( &mut self, entities: StringEntities, image_file: Option<String>, duration: f64, tr: f64, n_vols: usize, ) -> usize

pub fn create_node(&mut self, level: &str, entities: StringEntities) -> usize

pub fn get_run_node_mut(&mut self, index: usize) -> Option<&mut RunNode>

pub fn get_node_mut(&mut self, index: usize) -> Option<&mut Node>

pub fn find_nodes(&self, level: &str, entities: &StringEntities) -> Vec<usize>

Find nodes matching level and entities, sorted by subject/session/task/run.

pub fn get_or_create_node( &mut self, level: &str, entities: StringEntities, ) -> usize

Find or create a node.

pub fn get_or_create_run_node( &mut self, entities: StringEntities, image_file: Option<String>, duration: f64, tr: f64, n_vols: usize, ) -> usize

Find or create a run node.

pub fn get_run_collections( &self, entities: &StringEntities, ) -> Vec<RunVariableCollection>

Collect run-level variables into collections.
