Required Methods

fn as_any(&self) -> &dyn Any

fn n_data(&self) -> usize

fn p_out(&self) -> usize

fn transpose_mul( &self, axis: usize, v: &ArrayView1<'_, f64>, ) -> Result<Array1<f64>, BasisError>

fn forward_mul( &self, axis: usize, u: &ArrayView1<'_, f64>, ) -> Result<Array1<f64>, BasisError>

fn transpose_mul_second_diag( &self, axis: usize, v: &ArrayView1<'_, f64>, ) -> Result<Array1<f64>, BasisError>

fn transpose_mul_second_cross( &self, axis_d: usize, axis_e: usize, v: &ArrayView1<'_, f64>, ) -> Result<Array1<f64>, BasisError>

fn forward_mul_second_diag( &self, axis: usize, u: &ArrayView1<'_, f64>, ) -> Result<Array1<f64>, BasisError>

fn forward_mul_second_cross( &self, axis_d: usize, axis_e: usize, u: &ArrayView1<'_, f64>, ) -> Result<Array1<f64>, BasisError>

fn row_chunk_first( &self, axis: usize, rows: Range<usize>, ) -> Result<Array2<f64>, BasisError>

fn row_chunk_second_diag( &self, axis: usize, rows: Range<usize>, ) -> Result<Array2<f64>, BasisError>

fn row_chunk_second_cross( &self, axis_d: usize, axis_e: usize, rows: Range<usize>, ) -> Result<Array2<f64>, BasisError>

Provided Methods

fn row_vector_first_into( &self, axis: usize, row: usize, out: ArrayViewMut1<'_, f64>, ) -> Result<(), BasisError>

Single-row specialization of row_chunk_first. Default implementation delegates to row_chunk_first(axis, row..row+1) and copies the resulting row into the output buffer; implementations that can avoid the temporary matrix allocation should override this method.

fn as_materializable(&self) -> Option<&dyn MaterializablePsiDerivativeOperator>

Optional upcast to the dense materialization surface. Production exact paths should prefer the analytic matvec / row-chunk methods above and avoid forming the full derivative matrix; implementations that do support dense materialization (used by diagnostics, tests, and small-data fallbacks) should override this to return Some(self).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
