Member Function Documentation

TryParse()

static std::optional< SqlGuid > Lightweight::SqlGuid::TryParse ( std::string_view const &  text )

staticnoexcept

Parses a GUID from its 36-character xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx text form.

Any hex value is accepted, whatever its version and variant nibbles, as SQL Server's uniqueidentifier does. data[i] receives the i-th hex pair of the text, left to right.

Parameters

text	The GUID text, upper or lower case.

Returns

The parsed GUID, or std::nullopt if text is not a well-formed GUID.

UnsafeParse()

constexpr SqlGuid Lightweight::SqlGuid::UnsafeParse ( std::string_view const &  text )

staticconstexprnoexcept

Parses a GUID from a string. Use with caution and always prefer TryParse at all cost.

Accepts the same texts as TryParse(); for any other text it returns an unspecified sentinel.

Parameters

text	The GUID text.

Returns

The parsed GUID.
