size_t	operator() (const fourdst::atomic::Species &s) const noexcept
	Computes the hash for a Species object.

Detailed Description

Specialization of std::hash for fourdst::atomic::Species.

This allows fourdst::atomic::Species objects to be used as keys in unordered associative containers like std::unordered_map and std::unordered_set. The hash is computed based on the species' name (m_name), as it is expected to be a unique identifier for each species.

Usage Example

#include "fourdst/composition/atomicSpecies.h"
#include <unordered_map>
#include <string>
 
int main() {
    std::unordered_map<fourdst::atomic::Species, double> abundance;
    fourdst::atomic::Species h1("H1", ...);
    abundance[h1] = 0.999;
    return 0;
}
