Struct SceneBudgetState 

pub struct SceneBudgetState { /* private fields */ }

Mutable receipt for a SceneBudget as scene producers spend it.

Implementations

impl SceneBudgetState

pub fn new(budget: SceneBudget) -> Self

Start spending budget.

pub fn budget(&self) -> &SceneBudget

The immutable limits this state enforces.

pub fn nodes_used(&self) -> usize

Number of scene nodes admitted so far.

pub fn encoded_bytes_used(&self) -> usize

Number of approximate encoded bytes admitted so far.

pub fn admit( &mut self, depth: usize, face: Option<&str>, encoded_bytes: usize, ) -> Result<(), SceneBudgetExhausted>

Try to admit one node at depth with a visible face and encoded-size estimate. Returns a truncation reason when the budget is exhausted.
