Struct QuadratureRule 

pub struct QuadratureRule { /* private fields */ }
Description

Validated quadrature rule tied to one reference-cell topology.

Implementations§

§

impl QuadratureRule

Signature links:§QuadratureRule

pub fn new( reference_cell: ReferenceCell, polynomial_exactness: Option<usize>, points: Vec<QuadraturePoint>, ) -> Result<QuadratureRule, Diagnostic>

Signature links:newReferenceCellOptionusizeVecQuadraturePointResultQuadratureRuleDiagnostic

Construct a custom rule in any dimension.

polynomial_exactness is declarative evidence, not inferred. Use None for rules without a polynomial exactness contract.

§Errors

Returns EQ0804 for an empty rule, non-finite data, inconsistent point dimensions, points outside the reference cell, or non-positive total measure.

pub const fn reference_cell(&self) -> ReferenceCell

Signature links:reference_cellReferenceCell

Reference-cell topology and dimension.

pub const fn polynomial_exactness(&self) -> Option<usize>

Signature links:polynomial_exactnessOptionusize

Declared maximum total polynomial degree integrated exactly.

pub fn points(&self) -> &[QuadraturePoint]

Signature links:pointsQuadraturePoint

Ordered quadrature samples.

pub fn point() -> QuadratureRule

Signature links:pointQuadratureRule

Canonical measure-one rule for a reference point.

pub fn gauss_legendre(point_count: usize) -> Result<QuadratureRule, Diagnostic>

Signature links:gauss_legendreusizeResultQuadratureRuleDiagnostic

Gauss–Legendre rule on [-1, 1] with one to seven points.

§Errors

Returns EQ0804 for an unsupported point count.

pub fn tensor_product_gauss_legendre( dimension: usize, points_per_axis: usize, ) -> Result<QuadratureRule, Diagnostic>

Signature links:tensor_product_gauss_legendreusizeusizeResultQuadratureRuleDiagnostic

Tensor-product Gauss–Legendre rule on [-1, 1]^d.

§Errors

Returns EQ0804 for dimension zero, an unsupported one-dimensional point count, point-count overflow, or allocation failure.
