```
std::ostream & operator<< (std::ostream & out, const Uuid & uuid)
```
Writes Uuid.ToString() to the given stream.

```
std::string Generate ()
```
Generate a 128-bit (pseudo) random UUID in the form of version 4 as described

in RFC 4122, section 4.4.

The format of UUID version 4 must be xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx,

where y is one of [8, 9, A, B].

The hexadecimal values "a" through "f" are output as lower case characters.

Defined at line 120 of file ../../src/lib/uuid/uuid.cc
```
bool IsValid (const std::string & guid)
```
Returns true if the input string conforms to the version 4 UUID format.

Note that this does NOT check if the hexadecimal values "a" through "f"

are in lower case characters, as Version 4 RFC says they're

case insensitive. (Use IsValidOutputString for checking if the

given string is valid output string)

Defined at line 122 of file ../../src/lib/uuid/uuid.cc
```
bool IsValidOutputString (const std::string & guid)
```
Returns true if the input string is valid version 4 UUID output string.

This also checks if the hexadecimal values "a" through "f" are in lower

case characters.
