Detailed Description

Index of available weak reactions keyed by species.

Builds an in-memory map from the compiled weak-rate tables and provides simple query helpers to retrieve all weak reactions or those that involve a particular nuclide.

Implementation summary: the constructor iterates over UNIFIED_WEAK_DATA and inserts entries keyed by the parent Species. For each channel (β−, β+, e−-capture, e+-capture), if the tabulated log10(rate) is above the sentinel (-60), a WeakReactionEntry is pushed containing the grids t9, log10(rho*Ye), mu_e, the log10(rate), and the corresponding log10(neutrino loss) column.

Constructor & Destructor Documentation

WeakReactionMap()

gridfire::rates::weak::WeakReactionMap::WeakReactionMap

(

)

Construct the map by loading all weak reaction entries.

Postcondition

All valid reactions from the compiled data are available via get_all_reactions() and get_species_reactions(). Implementation: iterates UNIFIED_WEAK_DATA, filters any log(rate) <= -60, and groups entries by parent Species.

Member Function Documentation

get_all_reactions()

std::vector< WeakReactionEntry > gridfire::rates::weak::WeakReactionMap::get_all_reactions

(

)

const

Return a flat list of all weak reaction entries.

Returns

Vector of WeakReactionEntry records.

Example

WeakReactionMap map;
auto all = map.get_all_reactions();
// iterate or group as needed

get_species_reactions() [1/2]

std::expected< std::vector< WeakReactionEntry >, WeakMapError > gridfire::rates::weak::WeakReactionMap::get_species_reactions

(

const fourdst::atomic::Species &

species

)

const

Get all weak reaction entries for a given species.

Parameters

species

Nuclide to query (A,Z).

Returns

expected<vector<WeakReactionEntry>, WeakMapError> containing reactions on success or SPECIES_NOT_FOUND on failure.

Example

using fourdst::atomic::Species;
WeakReactionMap map;
Species fe52 = fourdst::atomic::az_to_species(52, 26);
if (auto res = map.get_species_reactions(fe52); res) {
    for (const auto& e : *res) { } // use e
} else {
    // handle WeakMapError::SPECIES_NOT_FOUND
}

get_species_reactions() [2/2]

std::expected< std::vector< WeakReactionEntry >, WeakMapError > gridfire::rates::weak::WeakReactionMap::get_species_reactions

(

const std::string &

species_name

)

const

Get all weak reaction entries for a given species by name.

Parameters

species_name

Symbolic name (e.g., "Fe52").

Returns

expected<vector<WeakReactionEntry>, WeakMapError> containing reactions on success or SPECIES_NOT_FOUND on failure.

Example

WeakReactionMap map;
if (auto res = map.get_species_reactions("Fe52"); res) {
    // use *res
}
