Method SetFromStringStrict

src/common/steamid.cpp:232–477

SetFromString allows many partially-correct strings, constraining how we might be able to change things in the future. SetFromStringStrict requires the exact string forms that we support and is preferred when the caller knows it's safe to be strict. Returns whether the string parsed correctly. The ID may still be invalid even if the string parsed correctly. If the string didn't parse correctly th

// still be invalid even if the string parsed correctly.
// If the string didn't parse correctly the ID will always be invalid.
