Struct VarTable 

pub struct VarTable { /* private fields */ }

The world’s variables, in slot order: shared across behaviors, so slots are assigned once across the whole set. A name the world’s Variables asset declares carries that declaration’s type and starting value; any other name a behavior mentions is an integer starting at zero.

Implementations

impl VarTable

pub fn declare(&mut self, name: &str, init: Val)

Declare a variable with its authored type and starting value. A repeated name keeps its first declaration; the world checker rejects duplicates.

pub fn slot_of(&self, name: &str) -> Option<u16>

The slot a name was assigned, if it has one.

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

Every declared name, in slot order.

pub fn initial(&self) -> Vec<Val>

The starting values, in slot order.

pub fn init_of(&self, name: &str) -> Option<Val>

The starting value a name was declared with, if it has a slot.
