Construct a guid object from RFC 4122 field values.

== Synopsis

Declared in `<bdlb_guid.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
Guid(
    unsigned long timeLow,
    unsigned short timeMid,
    unsigned short timeHiAndVersion,
    unsigned char clockSeqHiRes,
    unsigned char clockSeqLow,
    xref:BloombergLP/bsls/Types/Uint64.adoc[bsls::Types::Uint64] node);
----

== Description

Construct a guid object with an internal buffer composed from the specified `timeLow`, `timeMid`, `timeHiAndVersion`, `clockSeqHiRes`, `clockSeqLow`, and `node` as specified by RFC 4122. Note that only the least significant 48 bits of `node` are used in constructing the guid.

== Parameters
