Category:       Data, Data Structures
Synopsis:       An efficient finite map from (byte)strings to values.
Description:    An efficient finite map from (byte)strings to values.
                .
                The implementation is based on big-endian patricia
                trees, like "Data.IntMap". We first trie on the
                elements of "Data.ByteString" and then trie on the
                big-endian bit representation of those elements.
                Patricia trees have efficient algorithms for union
                and other merging operations, but they're also quick
                for lookups and insertions.
                .
                If you are only interested in being able to associate
                strings to values, then you may prefer the @hashmap@
                package which is faster for those only needing a
                map-like structure. This package is intended for
                those who need the extra capabilities that a trie-like
                structure can offer (e.g., structure sharing to
                reduce memory costs for highly redundant keys,
                taking the submap of all keys with a given prefix,
                contextual mapping, extracting the minimum and
                maximum keys, etc.)

----------------------------------------------------------------
Flag base4
    Default:     True
    Description: base-4.0 emits "Prelude deprecated" messages in
                 order to get people to be explicit about which
                 version of base they use.

Flag useCinternal
    Default:     False
    Description: Use optimized C implementation for indexOfDifference.
                 See notes in Data.Trie.ByteStringInternal.

Flag applicativeInBase
    Default:     True
    Description: Applicative functors were added in base-2.0

Flag bytestringInBase
    Default:     False
    Description: The bytestring library was included in base-2.0
                 and base-2.1.1, but for base-1.0 and base-3.0 it
                 was a separate package
