Overview ¶
Package elements holds the logic to encode and decode the BSON element types from native Go to BSON binary and vice versa.
These are low level helper methods, so they do not encode or decode BSON elements, only the specific types, e.g. these methods do not encode, decode, or identify a BSON element, so they won't read the identifier byte and they won't parse out the key string. There are encoder and decoder helper methods for the CString BSON element type, so this package can be used to parse keys.

Variables ¶
var ( Double DoubleNS String StringNS Document DocumentNS Array ArrayNS Binary BinNS ObjectID ObjectIDNS Boolean BooleanNS DateTime DatetimeNS Regex RegexNS DBPointer DBPointerNS JavaScript JavaScriptNS Symbol SymbolNS CodeWithScope CodeWithScopeNS Int32 Int32NS Timestamp TimestampNS Int64 Int64NS Decimal128 Decimal128NS CString CStringNS Byte BSONByteNS )
These variables are used as namespaces for methods pertaining to encoding individual BSON types.
var ErrTooSmall = errors.New("element: The provided slice is too small")
ErrTooSmall indicates that slice provided to encode into is not large enough to fit the data.
