示例1:
jsv.number, jsv.number, (im, k, v1, v2) =>
P.maybe(
false,
v3 => v3 === (v1 + v2),
IM.lookup(
k,
IM.alter(mv => P.just(P.maybe(v2, v3 => v3 + v2, mv)), k, IM.insert(k, v1, im))))示例2: intMapArb
jsv.property('alter can be used for insert', intMapArb(jsv.number), jsv.integer, jsv.number, (im, k, v) =>
P.maybe(
false,
v2 => v === v2,
IM.lookup(
k,
IM.alter(m => P.altMaybe(m, P.just(v)), k, IM.remove(k, im))
)
)示例3: co
return co(function* () {
yield takeAVar(needsRunning);
const a: A = yield maybe(set.task, identity, applyMaybe(modify, ma)) as Task<A>;
yield writeRef(currRef, right(a));
yield putAVar(responseVar, a);
yield delay(set.delay);
const responseVar_: AVar<A> = yield newEmptyAVar;
yield writeRef(currRef, left(responseVar_));
return loop(responseVar_, just(a));
});示例4: alter
return alter(mb => P.maybe(P.nothing, f, mb), k, m);
