Enum CubicCellKernelError 

pub enum CubicCellKernelError {
    InvalidInterval {
        reason: String,
    },
    InvalidCellShape {
        reason: String,
    },
    InsufficientMoments {
        reason: String,
    },
    BivariateNormalDomain {
        reason: String,
    },
}

Typed errors raised by the de-nested cubic transport kernel.

Sibling families (bernoulli_marginal_slope, survival_marginal_slope, marginal_slope_shared) currently consume the kernel’s public surface via Result<_, String>. To stay source-compatible, the kernel converts errors to String at the boundary via From<CubicCellKernelError> for String and keeps the public function signatures returning Result<_, String>. Display is exact-byte-equivalent to the previous format!(...) strings.

Variants

InvalidInterval

Interval probe / cell-bounds preconditions (ordered bounds, supported infinity patterns, positive finite width).

Fields

reason: String

InvalidCellShape

Cell-shape / branch-classification failure: tail cells not affine, finite cells with non-positive width, non-finite affine coefficients, non-affine cell with infinite bounds, leading-coefficient degeneracy in the moment recurrence, etc.

Fields

reason: String

InsufficientMoments

Reduced moment vector (or polynomial-convolution scratch) is shorter than the polynomial degree the leaf needs to evaluate.

Fields

reason: String

BivariateNormalDomain

Bivariate-normal CDF domain validation (non-finite/non-infinite argument, non-finite correlation).

Fields

reason: String

Trait Implementations

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
