Now that we've covered the contents of the package, we will look at how to use them with the standard package or in an application. Context is used in a few functions and methods of standard packages, mostly network packages. Let's go over them now:
- http.Server uses it with the Shutdown method so that it has full control over timeout or to cancel an operation.
- http.Request allows you to set a context using the WithContext method. It also allows you to get the current context using Context.
- In the net package, Listen, Dial, and Lookup have a version that uses Context to control deadlines and timeouts.
- In the database/sql package, context is used to stop or timeout many different operations.
