Implementations

impl DebrisPool

pub fn new() -> Self

pub fn alive_count(&self) -> usize

Number of currently alive particles.

pub fn capacity(&self) -> usize

Total pool capacity.

pub fn iter_alive(&self) -> impl Iterator<Item = &DebrisParticle>

Iterate over all alive particles (immutable).

pub fn iter_alive_mut(&mut self) -> impl Iterator<Item = &mut DebrisParticle>

Iterate over all alive particles (mutable).

pub fn particles(&self) -> &[DebrisParticle]

Access the raw particle slice (including dead particles).

pub fn particles_mut(&mut self) -> &mut [DebrisParticle]

Access the raw particle slice mutably.

pub fn reclaim_dead(&mut self)
