[英]Clojure async put! return value
Clojure async put! Clojure异步放! docs says (emphasis added)
docs说(添加了重点)
Asynchronously puts a val into port, calling fn0 (if supplied) when complete.
异步将val放入端口,完成后调用fn0(如果提供)。 nil values are not allowed.
不允许使用零值。 Will throw if closed.
如果关闭将抛出。 If on-caller?
如果是来电者? (default true) is true, and the put is immediately accepted, will call fn0 on calling thread.
(默认为true)为true,并且put被立即接受,将在调用线程上调用fn0。 Returns nil.
返回nil。
Yet the example code returns true 但是示例代码返回true
user=> (put! c "XYZ")
true
Are the docs incorrect or am I missing something? 文档不正确或我缺少什么吗?
This was fixed in this commit , the new doc string reads: 在此commit中已解决此问题 ,新的文档字符串显示为:
"Asynchronously puts a val into port, calling fn1 (if supplied) when complete, passing false iff port is already closed. nil values are not allowed. If on-caller? (default true) is true, and the put is immediately accepted, will call fn1 on calling thread. Returns true unless port is already closed."
