Enum QuadratureStatus 

pub enum QuadratureStatus {
    Evaluated,
    ToleranceNotMet,
    NotFinite,
    InvalidInterval,
}

How one lane of a quadrature batch ended.

Variant	last_value	Meaning
Evaluated	the integral	the rule ran to completion
ToleranceNotMet	best estimate — not to tolerance	adaptive lane ran out of subdivisions
NotFinite	NaN	the accumulated value was NaN or infinite
InvalidInterval	NaN	a limit is not finite

What Evaluated does and does not claim

For adaptive_quadrature_batch it means the requested tolerance was met. For a fixed QuadratureRule it means only that every node evaluated to a finite number and the sum is finite — it makes no accuracy claim at all, because a fixed rule has no way to know. Choosing enough panels for the integrand is the caller’s responsibility, and QuadratureSolution::error_estimate is NaN on that path for exactly this reason.

Units

Dimensionless — a status tag.

Variants

Evaluated

The rule ran to completion with a finite result.

ToleranceNotMet

Adaptive only: the subdivision budget or MAX_ADAPTIVE_DEPTH was reached before the tolerance. The reported value is the best estimate available and is not claimed to meet the tolerance.

NotFinite

The accumulated value is NaN or infinite — either the integrand returned a non-finite sample, or the sum overflowed.

InvalidInterval

A limit of the interval was infinite or NaN, so there is nothing to integrate over.

Implementations

impl QuadratureStatus

pub fn is_evaluated(self) -> bool

Whether this status means the lane produced a usable value.

Example

use outram_foam_basic_lib::ode::parallel::QuadratureStatus;

assert!(QuadratureStatus::Evaluated.is_evaluated());
assert!(!QuadratureStatus::ToleranceNotMet.is_evaluated());

pub fn label(self) -> &'static str

A short human-readable label, for log lines and failure reports.
