详细描述

Semantic version number with comparison and string-conversion helpers.

Used by NodeImpl::check_version() to compare a build-time application version against the live VLink library version. All components default to -1, which marks the value as not yet set.

成员函数说明

from_string()

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

staticnoexcept

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

Each component is decoded with std::from_chars; components missing from version_str retain the -1 sentinel.

参数

version_str

Source string such as "2.1.0".

返回

Parsed Version.

is_valid()

bool vlink::Version::is_valid ( ) const

noexcept

Returns whether every component has been set to a non-negative value.

返回

true when the version has been parsed or assigned explicitly.

operator!=()

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

noexcept

Tests inequality with target.

参数

target

Version to compare against.

返回

Logical negation of operator==.

operator<()

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

noexcept

Reports whether this version is strictly older than target.

Numeric ordering: compares major first, then minor, then patch.

参数

target

Version to compare against.

返回

true when this version is less than target.

operator==()

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

noexcept

Tests equality with target.

参数

target

Version to compare against.

返回

true when major, minor and patch all match.

operator>()

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

noexcept

Reports whether this version is strictly newer than target.

参数

target

Version to compare against.

返回

true when this version is greater than target.

to_string()

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

noexcept

Serialises this version back to a "major.minor.patch" string.

返回

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

类成员变量说明

major

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

Major version number; -1 when unset.

minor

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

Minor version number; -1 when unset.

patch

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

Patch version number; -1 when unset.
