checkForDupes :: (Data k, MonadThrow m) => Vector k -> m ()

Throws when duplicate keys are present in a vector.

checkReorder :: (Data k, MonadThrow m) => Vector k -> Vector k -> m ()

Throws when one vector is not a reordering of the other.

checkSubset :: (Data k, MonadThrow m) => [k] -> HashSet k -> m ()

Throws when any key is not present in the set.

makeLookup :: Data k => Vector k -> HashMap k Int

Builds a reverse lookup for the vector.

runLookup :: (Data k, MonadThrow m) => HashMap k Int -> Vector v -> k -> m v

Indexes into the vector of values, throwing on key missing or bad index.

reorder :: Data k => Vector k -> HashMap k Int -> Vector v -> Vector v

Reorders the vector of values by a new key order and an old lookup.

mergeKeys :: Data k => Vector k -> Vector k -> Vector (k, Int, Int)

Merges two key vectors and tags each with its provenance (favoring the second).

runIndexedLookup :: Vector (k, Int, Int) -> Vector v -> Vector v -> Vector v

Uses a merged key vector to select values.
