Struct VariableRegistry 

pub struct VariableRegistry { /* private fields */ }

Global variable registry for mapping between variable names and indices This allows user-facing string-based variable access while using efficient indices internally for performance-critical operations.

Implementations

impl VariableRegistry

pub fn new() -> Self

Create a new empty variable registry

pub fn register_variable(&mut self, name: &str) -> usize

Register a variable name and return its index If the variable already exists, returns its existing index

pub fn get_index(&self, name: &str) -> Option<usize>

Get the index for a variable name

pub fn get_name(&self, index: usize) -> Option<&str>

Get the name for a variable index

pub fn get_all_names(&self) -> &[String]

Get all registered variable names

pub fn len(&self) -> usize

Get the number of registered variables

pub fn is_empty(&self) -> bool

Check if the registry is empty

pub fn clear(&mut self)

Clear all registered variables

pub fn create_variable_map(&self, values: &[(String, f64)]) -> Vec<f64>

Create a variable mapping for evaluation Maps variable names to their values for use with eval_with_vars

pub fn create_ordered_variable_map(&self, values: &[f64]) -> Vec<f64>

Create a variable mapping from a slice of values in name order Assumes values are provided in the same order as variable registration
