Struct LaneProgram 

pub struct LaneProgram { /* private fields */ }

A lane program (RFC U3 §6). Send + Sync + Clone; it reads the forcing sets of the program it was built from.

Implementations

impl LaneProgram

pub fn layout(&self) -> &LaneLayout

The lane layout (RFC U3 §6): each variable a column-major block whose first axis is the lane (1..=capacity) and whose other axes are the variable’s axes outside the lane’s sets, in order.

pub fn capacity(&self) -> usize

The number of lanes the program was built for.

pub fn n_lane_inputs(&self) -> usize

The number of hoisted reads the pre-gather plan fills.

pub fn forcing_slots(&self) -> &[ForcingSlot]

The forcing slots a set for this program holds: the whole program’s.

pub fn new_workspace(&self) -> RhsWorkspace

Buffers for Self::eval_into and Self::eval_gathered_into.

pub fn eval_into( &self, u: &[f64], aux: &[f64], p: &[f64], t: f64, forcing: &ForcingSet, cells: &[i32], n: usize, du: &mut [f64], ws: &mut RhsWorkspace, ) -> Result<(), RhsError>

Evaluate lanes 1..=n (RFC U3 §6): for each lane l and each written variable, du holds the whole-domain program’s value at cells[:, l].

pub fn lane_inputs(&self) -> LaneInputs

The pre-gather plan’s buffers, unfilled.

pub fn gather_lane_inputs( &self, inputs: &mut LaneInputs, p: &[f64], t: f64, forcing: &ForcingSet, cells: &[i32], n: usize, ) -> Result<(), RhsError>

Fill inputs for lanes 1..=n of cells: every hoisted read of a non-state input, at each lane’s cell.

pub fn eval_gathered_into( &self, u: &[f64], aux: &[f64], inputs: &LaneInputs, p: &[f64], t: f64, cells: &[i32], n: usize, du: &mut [f64], ws: &mut RhsWorkspace, ) -> Result<(), RhsError>

Self::eval_into with every hoisted read taken from inputs, and the forcing set they were gathered from.

Trait Implementations

impl Clone for LaneProgram

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LaneProgram

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
