Struct infinity_sampler::Item

pub struct Item<T> { /* private fields */ }

A single item in the reservoir’s buffer. This is a thin wrapper over MaybeUninit that also tracks the insertion index and initialization state.

impl<T> Item<T>

pub fn take(&mut self) -> Option<T>

Take the value out of an item and reset its state.

pub unsafe fn take_unchecked(&mut self) -> T

Take the value out of an item without checking its state. UB if the item is empty.

pub fn write( &mut self, index: NonZeroUsize, value: T ) -> Option<(NonZeroUsize, T)>

Write a new value into an item, returning the old value

pub const unsafe fn assume_init_ref(&self) -> &T

Assume the item is not empty and return a reference. UB if the item is empty.
