Lazy +Data.Map

module Data.Map.Lazy
containers Data.Map.Lazy
An efficient implementation of ordered maps from keys to values (dictionaries). API of this module is strict in the keys, but lazy in the values. If you need value-strict maps, use Data.Map.Strict instead. The Map type itself is shared between the lazy and strict modules, meaning that the same Map value can be passed to functions in both modules (although that is rarely needed). These modules are intended to be imported qualified, to avoid name clashes with Prelude functions, e.g. > import qualified Data.Map.Lazy as Map The implementation of Map is based on size balanced binary trees (or trees of bounded balance) as described by: * Stephen Adams, "Efficient sets: a balancing act", Journal of Functional Programming 3(4):553-562, October 1993, http://www.swiss.ai.mit.edu/~adams/BB/. * J. Nievergelt and E.M. Reingold, "Binary search trees of bounded balance", SIAM journal of computing 2(1), March 1973. Note that the implementation is left-biased -- the elements of a first argument are always preferred to the second, for example in union or insert. Operation comments contain the operation time complexity in the Big-O notation (http://en.wikipedia.org/wiki/Big_O_notation).
package LazyVault
package
LazyVault is a sandboxing tool to install libraries and executables with a sandboxed environment. At the moment it's only supported under Unix or Gnu Systems. This package has only been tested under Gnu/Linux however. This program creates cabal sandboxes which you can use globally. For a detailed explaination on how this works refer to the README file found on the github page. Version 0.0.1
package lazy-csv
package
The CSV format is defined by RFC 4180. These efficient lazy parsers (String and ByteString variants) can report all CSV formatting errors, whilst also returning all the valid data, so the user can choose whether to continue, to show warnings, or to halt on error.  Valid fields retain information about their original location in the input, so a secondary parser from textual fields to typed values can give intelligent error messages. Version 0.5
package lazy-io
package
The library provides some basic but useful lazy IO functions. Keep in mind that lazy IO is generally discouraged. Perhaps a coroutine library (e.g. pipes) will better suit your needs. Version 0.1.0
package lazyarray
package
This package built on standard array package adds support for lazy monolithic arrays. Such arrays are lazy not only in their values, but in their indexes as well. Read the paper "Efficient Graph Algorithms Using Lazy Monolithic Arrays" (http://citeseer.ist.psu.edu/95126.html) for further details. Version 0.1.3
package lazyio
package
Run IO actions lazily while respecting their order. Running a value of the LazyIO monad in the IO monad is like starting a thread which is however driven by its output. That is, the LazyIO action is only executed as far as necessary in order to provide the required data. Version 0.0.3.2
package lazysmallcheck
package
Lazy SmallCheck is a library for exhaustive, demand-driven testing of Haskell programs.  It is based on the idea that if a property holds for a partially-defined input then it must also hold for all fully-defined refinements of the that input.  Compared to ``eager'' input generation as in SmallCheck, Lazy SmallCheck may require significantly fewer test-cases to verify a property for all inputs up to a given depth. Version 0.6
package lazysplines
package
See the source of Numeric.LazySplines.Examples for usage. Version 0.1
package MonadRandomLazy
package
Support for lazy computations which consume random values. Version 0.1
package NumLazyByteString
package
Num, Enum, Eq, Integral, Ord, Real, and Show instances for Lazy ByteStrings Version 0.0.0.1
package safe-lazy-io
package
Provides a safer API for incremental IO processing in a way very close to standard lazy IO. Version 0.1
package vector-functorlazy
package
Functor-lazy vectors perform the fmap operation in constant time, whereas other vectors require linear time.  All vector operations are supported except for slicing.  See http://github.com/mikeizbicki/vector-funxtorlazy for details on how this module works under the hood. Version 0.0.1
