Struct ToolLaneStats 

pub struct ToolLaneStats { /* private fields */ }

Live occupancy of the tool lane.

The lane reads an unbounded queue, so dispatch never blocks and a saturated lane is invisible from the outside: the batches just pile up. Counting what is queued, what is running, and what is parked on a wait is what makes that legible instead of guesswork.

Implementations

impl ToolLaneStats

pub fn new(workers: usize) -> Self

Stats for a lane that runs workers batches at a time.

pub fn enqueued(&self)

Record a batch handed to the lane.

pub fn queued(&self) -> usize

Batches waiting for lane capacity.

pub fn busy(&self) -> usize

Batches holding a permit and running.

pub fn parked(&self) -> usize

Batches parked on an unbounded wait, holding no capacity.

pub fn workers(&self) -> usize

The lane’s concurrency cap.

pub fn is_saturated(&self) -> bool

Whether every unit of capacity is taken and batches are waiting behind them.

fn fmt(&self, f: &mut Formatter<'_>) -> Result
