fromListS :: [(ByteString, a)] -> Trie abytestring-trie Data.Trie.Convenience This variant sorts the list before folding over it. This adds <math> overhead and requires the whole list be in memory at once, but it ensures that the list is in best-case order. The benefits generally outweigh the costs.
fromListWith :: (a -> a -> a) -> [(ByteString, a)] -> Trie abytestring-trie Data.Trie.Convenience A variant of fromListR that takes a function for combining values on conflict. The first argument to the combining function is the "new" value from the initial portion of the list; the second argument is the value that has been accumulated into the trie from the tail of the list (just like the first argument to foldr). Thus, fromList = fromListWith const.
fromListWith' :: (a -> a -> a) -> [(ByteString, a)] -> Trie abytestring-trie Data.Trie.Convenience A variant of fromListWith which applies the combining function strictly. This function is a good consumer for list fusion. If you need list fusion and are running into stack overflow problems with fromListWith, then this function may solve the problem.
fromListWithL :: (a -> a -> a) -> [(ByteString, a)] -> Trie abytestring-trie Data.Trie.Convenience A left-fold variant of fromListWith. Note that the arguments to the combining function are swapped: the first is the value in the trie which has been accumulated from the initial part of the list; the second argument is the "new" value from the remaining tail of the list (just like the first argument to foldl). Thus, fromListL = fromListWithL const.
fromListWithL' :: (a -> a -> a) -> [(ByteString, a)] -> Trie abytestring-trie Data.Trie.Convenience A variant of fromListWithL which applies the combining function strictly.
