Struct RequestQueue 

pub struct RequestQueue { /* private fields */ }

Implementations

impl RequestQueue

pub fn new(capacity: usize) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn is_full(&self) -> bool

pub fn push(&mut self, req: PriorityRequest) -> Result<(), PriorityRequest>

Enqueue. Caller must already have classified the priority. Returns Err carrying the request if full. The request is boxed so the Result doesn’t carry a fat Err variant on the happy path (queue mailboxes pass this around frequently).

pub fn pop(&mut self) -> Option<PriorityRequest>
