ReactiveX.io documentation使用AnonymousDisposable
,它位于RxSwift 2.x中,但是在RxSwift 3.0中是未解析的标识符。我该怎么用?
let source = Observable.create { observer in
for i in 1...5 {
observer.on(.Next(i))
}
observer.on(.Completed)
// Note that this is optional. If you require no cleanup you can return
// NopDisposable.instance
return AnonymousDisposable {
print("Disposed")
}
}
source.subscribe {
print($0)
}

请注意Swift 2中的这种语法:
NopDisposable.instance
也被替换为
Disposables.create()
除此之外,有趣的是,在引擎盖下,NopDisposable
仍然存在但通过此create
方法公开。 Here's the source

使用:
def compute(bigrams, table):
"""Yield a resultant operation for each bigram."""
for bigram in bigrams:
# Get values and convert strings
x = int(table[bigram[0]])
y = int(table[bigram[1]])
z = int(bigram[2])
operation = (x * y) / z
yield operation
list(compute(list_2, dict(list_1)))
# [12.5, 15.0]
