V8 Serialization Format Constants
Enums and constant values for the V8 serialization format.
constants.kLatestVersion
constants.kLatestVersion
The current supported serialization format implemented here.
constants.SerializationTag
constants.SerializationTag()
1-byte tags used to identify the type of the next value.
Notes
These tags are defined in the SerializationTag enum in the v8 src.

None |
| kTrue | true |
True |
| kFalse | false |
False |
