ruster

Ruster is a library using ffi for database management with psql/pg_dump + mysql/mysqldump written in Rust.

The generated C static and shared libraries can be reused in other languages (Golang for example).

Build ruster

The build of project produces 2 go binaries, 1 static library (libruster.a) and 1 shared library (libruster.so).

The headers of C functions are in lib/ruster.h and must be present before code generation.

make build-shared

make build-static

Using ruster

PostgreSQL

/*
#cgo LDFLAGS: -L./lib -lruster
#include "./lib/ruster.h"
*/
import "C"

import (
     "os"
)

func main() {
  os.Getenv("PGPASSWORD")
  err := func() error {
    C.pg_dump_database(
    C.CString("localhost"),
    C.CString("5432"),
    C.CString("postgres"),
    C.CString("postgres"),
    C.CString("pg_dump.sql"),
    C.CString("true"),
    );
     return nil
   }
   if err() == nil {
    func() {
      C.psql_restore_database(
      C.CString("localhost"),
      C.CString("5432"),
      C.CString("postgres"),
      C.CString("postgres"),
      C.CString("pg_dump.sql"),
      C.CString("true"),
      );
    }()
  }
}

MySQL - Mariadb

/*
#cgo LDFLAGS: -L./lib -lruster
#include "./lib/ruster.h"
*/
import "C"

import (
     "os"
)

func main() {
  os.Getenv("MYSQL_PWD")
  err := func() error {
    C.mysqldump_database(
      C.CString("localhost"),
      C.CString("3306"),
      C.CString("root"),
      C.CString("mysql"),
      C.CString("dump.sql"),
      C.CString("true"),
    );
      return nil
  }
  time.Sleep(time.Duration(250)*time.Millisecond)
  if err() == nil {
    func() {
      C.mysql_restore_database(
        C.CString("localhost"),
        C.CString("3306"),
        C.CString("root"),
        C.CString("mysql"),
        C.CString("dump.sql"),
        C.CString("true"),
