Channel methods

V exposes some public methods to control a channel's behavior. These methods include the following:

• try_push()
• try_pop()
• close()

Except for the close() method, the try_push() and try_pop() methods have a return value, which is a built-in enum type called ChanState. The ChanState enum has three enum values:

• not_ready
• closed
• success

Performing try_push() or try_pop() on a channel can return one of the three aforementioned states. In this section, we will learn how to work with the try_push() function with buffered and unbuffered channels and then we cover how to work with the try_pop() and close() methods.

Using try_push() on unbuffered channels

try_push() gracefully pushes data into the channel and returns the status in the form of an enum value from ChanState. The try_push() method accepts values of the type that the channel accepts. For an unbuffered channel, the try_push() operation returns a .not_ready value...
