Struct File Mapper

Struct File Mapper uses Filesystem in Userspace feature in Linux systems to map in-memory data (user struct) to accessible file system.

Package

• Get the package:

go get github.com/IslamWalid/struct_file_mapper

Usage and Example

package main

import (

	"os/signal"
	"syscall"

	sfmapper "github.com/IslamWalid/struct_file_mapper"
)

	Age    int
}

func main() {
    p := &Person{
    	Name: "Islam",
    	Age:  22,
    }

    // Create signal to recieve ctrl+c
    sigs := make(chan os.Signal)
    signal.Notify(sigs, syscall.SIGINT)

    go func() {
        <- sigs
        sfmapper.UnMount("person")
    }()

    // Create directory person to host the filesystem
    os.MkdirAll("person", 0777)

    // Start the filesystem
    err := sfmapper.Mount("person", p)
    if err != nil {
        fmt.Fprint(os.Stderr, err)
        os.Exit(1)
