// Package bson is a library for reading, writing, and manipulating BSON. The
|
||
|
|
// library has two families of types for representing BSON.
|
||
|
|
//
|
||
|
|
// The Raw family of types is used to validate and retrieve elements from a slice of bytes. This
|
||
|
|
// type is most useful when you want do lookups on BSON bytes without unmarshaling it into another
|
||
|
|
// type.
|
||
|
|
//
|
||
|
|
// Example:
|
||
|
|
// var raw bson.Raw = ... // bytes from somewhere
|
||
|
|
// err := raw.Validate()
|
||
|
|
// if err != nil { return err }
|
||
|
|
// val := raw.Lookup("foo")
|
||
|
|
// i32, ok := val.Int32OK()
|
||
|
|
// // do something with i32...
|
||
|
|
//
|
||
|
|
// The D family of types is used to build concise representations of BSON using native Go types.
|
||
|
|
// These types do not support automatic lookup.
|
||
|
|
//
|
||
|
|
// Example:
|
||
|
|
// bson.D{{"foo", "bar"}, {"hello", "world"}, {"pi", 3.14159}}
|
||
|
|
//
|
||
|
|
//
|
||
|
|
// Marshaling and Unmarshaling are handled with the Marshal and Unmarshal family of functions. If
|
||
|
|
// you need to write or read BSON from a non-slice source, an Encoder or Decoder can be used with a
|
||
|
|
// bsonrw.ValueWriter or bsonrw.ValueReader.
|
||
|
|
//
|
||
|
|
// Example:
|
||
|
|
// b, err := bson.Marshal(bson.D{{"foo", "bar"}})
|
||
|
|
// if err != nil { return err }
|
||
|
|
// var fooer struct {
|
||
|
|
// Foo string
|
||
|
|
// }
|
||
|
|
// err = bson.Unmarshal(b, &fooer)
|
||
|
|
// if err != nil { return err }
|
||
|
|
// // do something with fooer...
|
