Member Function Documentation

operator<=>()

std::strong_ordering SemVer::operator<=>

(

const SemVer &

other

)

const

Compare two SemVer objects.

This is a custom operator implementation (instead of default) due due to the way semver handles "pre-release" information. If a SemVer has a pre-release extension, it is considered older (less than) than the same SemVer without that extension. This means that simple field-by-field compare cannot be done, as the pre-release would normally require lexicographical comparison and count anything longer as "greater than", which is the opposite of what's desired.

parse()

std::expected< SemVer, Parser::Error > SemVer::parse ( std::string_view input )

inlinestatic

Parse a SemVer from a string.

This is just a helper object to construct the parser and run it

Parameters

input

The string to parse

Returns

std::expected<SemVer, Parser::Error> Either the successfully parsed SemVer, or the Error that arose during parsing.
