Detailed Description

Semantic version number with comparison and string conversion utilities.

Used by NodeImpl::check_version() to compare the compile-time VLink version against the runtime library version. All fields default to -1 (invalid).

Member Function Documentation

from_string()

Version vlink::Version::from_string ( const std::string & version_str )

staticnodiscardnoexcept

Parses a version string in "major.minor.patch" format.

Uses std::from_chars for each component; components missing from the string remain -1.

Parameters

version_str

String such as "2.1.0".

Returns

Parsed Version; any missing component stays -1.

is_valid()

bool vlink::Version::is_valid ( ) const

nodiscardnoexcept

Returns true when all three components are non-negative.

Returns

true if the version was successfully parsed or explicitly set.

Here is the call graph for this function:

Here is the caller graph for this function:

operator!=()

bool vlink::Version::operator!= ( const Version & target ) const

nodiscardnoexcept

Returns true when versions differ.

Parameters

target

Version to compare against.

Returns

Logical negation of operator==.

operator<()

bool vlink::Version::operator< ( const Version & target ) const

nodiscardnoexcept

Returns true when this version is older than target.

Compares major first, then minor, then patch (numeric order).

Parameters

target

Version to compare against.

Returns

true if this version is strictly less than target.

operator==()

bool vlink::Version::operator== ( const Version & target ) const

nodiscardnoexcept

Returns true when both versions are identical.

Parameters

target

Version to compare against.

Returns

true if major, minor, and patch are all equal.

operator>()

bool vlink::Version::operator> ( const Version & target ) const

nodiscardnoexcept

Returns true when this version is newer than target.

Parameters

target

Version to compare against.

Returns

true if this version is strictly greater than target.

to_string()

std::string vlink::Version::to_string ( ) const

nodiscardnoexcept

Converts this version to a "major.minor.patch" string.

Returns

Formatted version string, e.g. "2.1.0".

Member Data Documentation

major

int vlink::Version::major {-1}

Major version number; -1 if not set.

minor

int vlink::Version::minor {-1}

Minor version number; -1 if not set.

patch

int vlink::Version::patch {-1}

Patch version number; -1 if not set.
