pgparser

Overview

This package can unpack complex types from Postgres into structs, slices, and primitive values.

Example

Also see example_test.go in this directory.

import (
  "fmt"

  "fknsrs.biz/p/pgparser"
)

func ExampleParse() {
  var s = `(a,{x,y,z},5)`

  var v struct{
    A string
    B []string
    C int
  }

  if err := pgparser.Unmarshal(s, &v); err != nil {
    panic(err)
  }

  fmt.Printf("%#v\n", v)

  // Output:
  // struct { A string; B []string; C int }{A:"a", B:[]string{"x", "y", "z"}, C:5}
}

Functions

func Unmarshal

func Unmarshal(s string, v interface{}) error

Unmarshal takes a string representation of a complex type from Postgres and unpacks it into value v. Since the serialised data doesn't include field names or even types, values must match perfectly to be decoded. This means that structs must have their fields in the same order as they are in the database, and those fields must be the same types.
