+# Context
+
+This module defines the Context type, which carries deadlines, cancellation signals,
+and other request-scoped values across API boundaries 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 with_cancel,
+with_deadline, with_timeout, or with_value. When a Context is canceled, all Contexts
+derived from it are also canceled.
+
+The with_cancel, with_deadline, and with_timeout functions take a Context (the parent)
+and return a derived Context (the child). Calling the cancel function
+cancels the child and its children, removes the parent's reference to the child,
+and stops any associated timers.
+
+Programs that use Contexts should follow these rules to keep interfaces consistent
+across different modules.
+
+Do not store Contexts inside a struct type; instead, pass a Context explicitly
+to each function that needs it. The Context should be the first parameter,
+typically named ctx, just to make it more consistent.
+
+## Examples
+
+In this section you can see some usage examples for this module
+
+### Context With Cancellation
+
+```v
+import context
+
+// This example demonstrates the use of a cancelable context to prevent a
+// routine leak. By the end of the example function, the routine started
+// by gen will return without leaking.
+fn example_with_cancel() {
+	// gen generates integers in a separate routine and
+	// sends them to the returned channel.
+	// The callers of gen need to cancel the context once
+	// they are done consuming generated integers not to leak
+	// the internal routine started by gen.
+	gen := fn (ctx context.Context) chan int {
+		dst := chan int{}
+		go fn (ctx context.Context, dst chan int) {
+			mut v := 0
+			ch := ctx.done()
+			for {
+				select {
+					_ := <-ch {
+						// returning not to leak the routine
+						return
+					}
+					dst <- v {
+						v++
+					}
+				}
+			}
+		}(ctx, dst)
+		return dst
+	}
+
+	ctx := context.with_cancel(context.background())
+	defer {
+		context.cancel(ctx)
+	}
+
+	ch := gen(ctx)
+	for i in 0 .. 5 {
+		v := <-ch
+		assert i == v
+	}
+}
+```
+
+### Context With Deadline
+
+```v
+import context
+import time
+
+const (
+	// a reasonable duration to block in an example
+	short_duration = 1 * time.millisecond
+)
+
+// This example passes a context with an arbitrary deadline to tell a blocking
+// function that it should abandon its work as soon as it gets to it.
+fn example_with_deadline() {
+	dur := time.now().add(short_duration)
+	ctx := context.with_deadline(context.background(), dur)
+
+	defer {
+		// Even though ctx will be expired, it is good practice to call its
+		// cancellation function in any case. Failure to do so may keep the
+		// context and its parent alive longer than necessary.
+		context.cancel(ctx)
+	}
+
+	ctx_ch := ctx.done()
+	select {
+		_ := <-ctx_ch {}
+		1 * time.second {
+			panic('This should not happen')
+		}
+	}
+}
+```
+
+### Context With Timeout
+
+```v
+import context
+import time
+
+const (
+	// a reasonable duration to block in an example
+	short_duration = 1 * time.millisecond
+)
+
+// This example passes a context with a timeout to tell a blocking function that
+// it should abandon its work after the timeout elapses.
+fn example_with_timeout() {
+	// Pass a context with a timeout to tell a blocking function that it
+	// should abandon its work after the timeout elapses.
+	ctx := context.with_timeout(context.background(), short_duration)
+	defer {
+		context.cancel(ctx)
+	}
+
+	ctx_ch := ctx.done()
+	select {
+		_ := <-ctx_ch {}
+		1 * time.second {
+			panic('This should not happen')
+		}
+	}
+}
+```
+
+### Context With Value
+
+```v
+import context
+
+type ValueContextKey = string
+
+// This example demonstrates how a value can be passed to the context
+// and also how to retrieve it if it exists.
+fn example_with_value() {
+	f := fn (ctx context.Context, key ValueContextKey) string {
+		if value := ctx.value(key) {
+			if !isnil(value) {
+				return *(&string(value))
+			}
+		}
+		return 'key not found'
+	}
+
+	key := ValueContextKey('language')
+	value := 'VAL'
+	ctx := context.with_value(context.background(), key, &value)
+
+	assert value == f(ctx, key)
+	assert 'key not found' == f(ctx, ValueContextKey('color'))
+}
+```
