◆ StringValue() [1/2]

constexpr Quantum::Number::StringValue::StringValue ( )

constexprdefault

Default initializer to a zero-first solution.

◆ StringValue() [2/2]

constexpr Quantum::Number::StringValue::StringValue ( std::string_view s )

inlineexplicitconstexpr

Set to expected value from a view of something at most N-char long.

This means that we will need to either redesign quantum numbers or make an exception for the type, e.g., is \tilde{X} perhaps OK as ~X? We have no opinion at this moment
