Struct RuntimePropertiesStackFrame 

pub struct RuntimePropertiesStackFrame { /* private fields */ }

Data structure for a single frame of our runtime stack, including a reference to its parent frame and properties for runtime evaluation, e.g. of Expressions. RuntimePropertiesStackFrames also track timeline playhead position.

Components push RuntimePropertiesStackFrames before computing properties and pop them after computing, thus providing a hierarchical store of node-relevant data that can be bound to symbols in expressions.

Implementations

impl RuntimePropertiesStackFrame

pub fn new(symbols_within_frame: HashMap<String, Variable>) -> Rc<Self>

pub fn push( self: &Rc<Self>, symbols_within_frame: HashMap<String, Variable>, ) -> Rc<Self>

pub fn pop(self: &Rc<Self>) -> Option<Rc<Self>>

pub fn resolve_symbol_as_variable(&self, symbol: &str) -> Option<Variable>

pub fn resolve_symbol_as_erased_property( &self, symbol: &str, ) -> Option<UntypedProperty>

pub fn resolve_symbol(&self, symbol: &str) -> Option<Variable>
