Expand description

Trait each subgrid must implement.

Required Methods§

source

fn mu2_grid(&self) -> Cow<'_, [Mu2]>

Return a slice of Mu2 values corresponding to the (squared) renormalization and factorization values of the grid. If the subgrid does not use a grid, this method should return an empty slice.

source

fn x1_grid(&self) -> Cow<'_, [f64]>

Return a slice of values of x1. If the subgrid does not use a grid, this method should return an empty slice.

source

fn x2_grid(&self) -> Cow<'_, [f64]>

Return a slice of values of x2. If the subgrid does not use a grid, this method should return an empty slice.

source

fn convolute( &self, x1: &[f64], x2: &[f64], mu2: &[Mu2], lumi: &mut dyn FnMut(usize, usize, usize) -> f64 ) -> f64

Convolute the subgrid with a luminosity function, which takes indices as arguments that correspond to the entries given in the slices x1, x2 and mu2.

source

fn fill(&mut self, ntuple: &Ntuple<f64>)

Fills the subgrid with weight for the parton momentum fractions x1 and x2, and the scale q2. Filling is currently only support where both renormalization and factorization scale have the same value.
