Interface: ConcurrencyLimiter
Defined in: limiter.ts:176
Minimal contract for capping concurrent Source.fetch calls. An
implementation hands out slots scoped however it likes; the default
PerOriginSemaphore scopes per url.origin.
Methods
acquire()
acquire(
url,signal?,getPriority?):Promise<() =>void>
Defined in: limiter.ts:189
Acquire a slot to perform one fetch to url. Resolves to a release
function — call it exactly once when the fetch settles. If signal
aborts while waiting in the queue, the returned promise rejects with the
signal's reason and no slot is consumed.
getPriority is an optional callback re-evaluated by the limiter on
every slot-open, so queued waiters can be re-ordered if their priority
depends on dynamic state (e.g. distance from viewport center, which
changes on pan). Lower-numeric = serviced sooner. A tuple sorts
lexicographically. Omitted = priority 0, FIFO among ties.
Parameters
url
signal?
getPriority?
() => Priority
Returns
Promise<() => void>
