Struct ExpressionTrackedObjects 

pub struct ExpressionTrackedObjects { /* private fields */ }

The distinct objects an expression reads from, in the order they were first added.

Implementations

impl ExpressionTrackedObjects

pub fn new() -> Self

Creates an empty collection.

pub fn add(&mut self, obj: &dyn IExpressionObject, member: &str)

pub fn add_key(&mut self, obj: ExpressionObjectKey, _member: &str)

Tracks an object given by its identity key.

pub fn clear(&mut self)

Removes every tracked object.

pub fn iter(&self) -> Iter<'_, ExpressionObjectKey>

Enumerates the tracked objects in the order they were first added.
