Data.BEncode.BDict

Contents

Description

This module defines a simple key/value list ordered by keys which both faster and more suitable for bencode dictionaries than just [(k,v)].

Construction

empty :: BDictMap a Source #

O(1). The empty dicionary.

singleton :: BKey -> a -> BDictMap a Source #

O(1). Dictionary of one key-value pair.

Query

null :: BDictMap a -> Bool Source #

O(1). Is the dictionary empty?

member :: BKey -> BDictMap a -> Bool Source #

O(n). Is the key a member of the dictionary?

lookup :: BKey -> BDictMap a -> Maybe a Source #

O(n). Lookup the value at a key in the dictionary.

Combine

union :: BDictMap a -> BDictMap a -> BDictMap a Source #

O(n + m). Merge two dictionaries by taking pair from both given dictionaries. Dublicated keys are not filtered.

Maps

map :: (a -> b) -> BDictMap a -> BDictMap b Source #

O(n). Map a function over all values in the dictionary.

mapWithKey :: (BKey -> a -> b) -> BDictMap a -> BDictMap b Source #

O(n). Map a function over all keys/value pairs in the dictionary.

Folds

foldMapWithKey :: Monoid m => (BKey -> a -> m) -> BDictMap a -> m Source #

O(n). Map each key/value pair to a monoid and fold resulting sequnce using mappend.

bifoldMap :: Monoid m => (BKey -> a -> m) -> BDictMap a -> m Source #

Deprecated: Use foldMapWithKey instead

O(n). Map each key/value pair to a monoid and fold resulting sequnce using mappend.

Conversion

fromAscList :: [(BKey, a)] -> BDictMap a Source #

O(n). Build a dictionary from a list of key/value pairs where the keys are in ascending order.

toAscList :: BDictMap a -> [(BKey, a)] Source #

O(n). Convert the dictionary to a list of key/value pairs where the keys are in ascending order.
