Enum ProductMeasure 

pub enum ProductMeasure {
    Uniform,
    Named(MeasureName),
    Product(Vec<ProductMeasure>),
}

Product measure over one or more continuous axes.

Uniform is the Lebesgue measure scaled by interval width (requires bounded intervals; V8 rejects unbounded + Uniform). Named(D) is a probability distribution with proper density over its declared support — Normal, Exponential, Pareto, Beta, etc. Product(_) carries a per-axis product of measures for K-D continuous cartesians.

Variants

Uniform

Lebesgue measure scaled to the interval; needs bounded intervals.

Named(MeasureName)

A named probability distribution over its support.

Product(Vec<ProductMeasure>)

One measure per axis.

Implementations

impl ProductMeasure

pub fn is_integrable(&self, intervals: &[Interval]) -> bool

true if this measure has finite total mass given the supplied intervals. Used by V8.

• Uniform is integrable iff every interval is bounded.
• Named(D) is integrable per its distribution: proper probability distributions are always integrable (they have unit total mass by definition).
• Product(children) is integrable iff every child is.
