Struct BatchInversion 

pub struct BatchInversion<P: PackedField> { /* private fields */ }

Reusable batch inversion context that owns its scratch buffers.

Reusing one instance across many same-size calls avoids reallocating on every call.

Implementations

impl<P: PackedField> BatchInversion<P>

pub fn new(n: usize) -> Self

Creates a new batch inversion context sized for n packed elements.

Arguments

• n: the number of packed elements every future call must be invoked with.

Panics

Panics if n is 0.

pub fn invert_nonzero(&mut self, elements: &mut [P])

Inverts every element of the slice in place.

Arguments

• elements: the slice to invert in place.

Safety

Every scalar element must be non-zero. Behavior is undefined if any scalar is zero.

Panics

Panics if the slice length does not equal the n given at construction.

pub fn invert_or_zero(&mut self, elements: &mut [P])

Inverts every element of the slice in place, leaving zero elements as zero.

Arguments

• elements: the slice to invert in place.

Panics

Panics if the slice length does not equal the n given at construction.
