Struct PrimitiveArena 

pub struct PrimitiveArena<'f, P> { /* private fields */ }

Hands out packets from caller storage as &'f mut P, one slot each.

The storage is borrowed for 'f, so it cannot be reused (a new arena over it, say) while any packet it handed out is still linked into a frame.

Implementations

impl<'f, P> PrimitiveArena<'f, P>

pub fn new(storage: &'f mut [P]) -> Self

Hand out the slots of storage, front to back.

pub fn push(&mut self, packet: P) -> Option<&'f mut P>

Store packet in the next free slot and return it for the rest of 'f; None once the storage is used up.

pub fn len(&self) -> usize

Slots handed out so far.

pub fn is_empty(&self) -> bool

True if nothing was handed out yet.

pub fn remaining(&self) -> usize

Slots still free.
