Structure-of-Arrays layout for particle data.

Stores each field component in a separate contiguous array for cache-friendly SIMD access. Use from_aos and to_aos to convert to/from FluidParticle slices.

Implementations

impl ParticleSoa

pub fn new() -> Self

Create an empty SOA store.

pub fn with_capacity(n: usize) -> Self

Create a SOA store with given capacity.

pub fn len(&self) -> usize

Number of particles.
