go fiber http functions-CodePudding

On the home page of "gofiber.io" they show this code

package main

import (
    "log"

    "github.com/gofiber/fiber/v2"
)

func main() {
    app := fiber.New()

    app.Get("/", func (c *fiber.Ctx) error {
        return c.SendString("Hello, World!")
    })

    log.Fatal(app.Listen(":3000"))
}

In the code, the function inside the second argument of the "Get" function says it is returning an error but returns a c.SendString("Hello, World!"). What do I not understand about this that makes it ok to say you're returning an error but you are returning something else?

I admit I am new to Golang and even newer to Go Fiber so please help me understand this better.

CodePudding user response：

The resulting error is returned from SendString (nil, if no error)

See https://docs.gofiber.io/api/ctx#send

The signature for is:

func (c *Ctx) SendString(body string) error
