Struct DerivativeBatch 

pub struct DerivativeBatch { /* private fields */ }

The result of derivative_batch — one DerivativeSolution per point, in point order.

Implementations

impl DerivativeBatch

pub fn solutions(&self) -> &[DerivativeSolution]

Every lane’s solution, in the order the points were supplied.

pub fn into_solutions(self) -> Vec<DerivativeSolution>

Consume the batch, yielding the per-lane solutions.

pub fn len(&self) -> usize

Number of lanes.

pub fn is_empty(&self) -> bool

Whether the batch has no lanes.

pub fn get(&self, i: usize) -> Option<DerivativeSolution>

Lane i’s solution, or None if i is out of range.

pub fn all_ok(&self) -> bool

Whether every lane produced a usable derivative.

pub fn failure_count(&self) -> usize

How many lanes failed.

pub fn first_failure(&self) -> Option<(usize, DerivativeSolution)>

The first failing lane and its solution, if any.

pub fn failures(&self) -> Vec<(usize, DerivativeSolution)>

Every failing lane and its solution.

pub fn values(&self) -> Result<Vec<f64>, DiffBatchFailure>

Every lane’s derivative, all or nothing.

Errors

DiffBatchFailure naming the failure count and the first failing lane if any lane failed. A partially-NaN Vec<f64> is never returned.

pub fn check_all_ok(&self) -> Result<(), DiffBatchFailure>

Err describing the first failure, if any lane failed.

Errors

DiffBatchFailure as for Self::values.
