I intentionally wrote a panic handler, but the request never returned. Is this a bug?

as the title said, the code is [blow:

It's not a bug. nbio is designed at the basic level as net/http.

When we try this:

package main

import (
    "fmt"
    "net/http"
)

func main() {
    http.HandleFunc("/hello", func(w http.ResponseWriter, req *http.Request) {
        fmt.Fprintf(w, "hello")
    })
    http.HandleFunc("/panic", func(w http.ResponseWriter, req *http.Request) {
        panic(nil)
    })

    http.ListenAndServe(":8080", nil)
}

We also can't get the response because of the panic.

But when we use some other frameworks, such as gin:

package main

import "github.com/gin-gonic/gin"

func main() {
    r := gin.Default()
    r.GET("/hello", func(c *gin.Context) {
        c.String(200, "hello")
    })
    r.GET("/panic", func(c *gin.Context) {
        panic(nil)
    })
    r.Run(":8080")
}

We get 500 Internal Server Error

Whatever, the best way is to use recover middleware.
