Channel properties

You can obtain information about a channel variable by accessing the properties it exposes. The properties of the channel include len, cap, and closed. These properties provide the following information about a channel at the time of accessing them:

• cap is an integer property that indicates the capacity of the channel. This is 0 for the unbuffered channel. In the case of a buffered channel, the cap property indicates the maximum number of values a channel can hold.
• len is an integer property that indicates the actual number of values that the channel holds at the time of accessing this property. At any given point in time, the len value can only be less than or equal to the cap property.
• closed is a Boolean property, and when its value is true, it indicates that the channel is closed. If a channel is not closed, the value of the closed property will be false.
