// Package context defines the Context type, which carries deadlines,

// and between processes.
|
|
||||||
//
|
|

// Incoming requests to a server should create a Context, and outgoing
|
|
||||||
// calls to servers should accept a Context. The chain of function
|
|
||||||
// calls between them must propagate the Context, optionally replacing
|
|
||||||
// it with a derived Context created using WithCancel, WithDeadline,
|
|
||||||
// WithTimeout, or WithValue. When a Context is canceled, all
|
|
||||||
// Contexts derived from it are also canceled.
|
|
||||||
//
|
|
||||||
// The WithCancel, WithDeadline, and WithTimeout functions take a
|
|
||||||
// Context (the parent) and return a derived Context (the child) and a
|
|
||||||
// CancelFunc. Calling the CancelFunc cancels the child and its
|
|
||||||
// children, removes the parent's reference to the child, and stops
|
|
||||||
// any associated timers. Failing to call the CancelFunc leaks the
|
|
||||||
// child and its children until the parent is canceled or the timer
|
|
||||||
// fires. The go vet tool checks that CancelFuncs are used on all
|
|
||||||
// control-flow paths.
|
|
||||||
//
|
|
||||||
// Programs that use Contexts should follow these rules to keep interfaces
|
|
||||||
// consistent across packages and enable static analysis tools to check context
|

//
