func Clone ¶
Clone creates a new Context object but inherits values from the base context object.
Example ¶
package main
import (
"context"
"fmt"
"github.com/izumin5210/clonectx"
)
func main() {
debug := func(ctx context.Context) {
fmt.Println(
"user_id: ", ctx.Value("user_id"), "\t",
"request_id: ", ctx.Value("request_id"), "\t",
"error: ", ctx.Err(),
)
}
baseCtx, cancel := context.WithCancel(context.Background())
baseCtx = context.WithValue(baseCtx, "user_id", 123)
baseCtx = context.WithValue(baseCtx, "request_id", "7de4f345-8a68-47bc-a1df-90299f95d753")
newCtx := clonectx.Clone(baseCtx)
cancel()
debug(baseCtx)
debug(newCtx)
}
Output: user_id: 123 request_id: 7de4f345-8a68-47bc-a1df-90299f95d753 error: context canceled user_id: 123 request_id: 7de4f345-8a68-47bc-a1df-90299f95d753 error: <nil>
