Description

This internal module is exposed only for testing and benchmarking. You don't need to import it.

Synopsis

Documentation

data StateQueue a Source #

StateQueue is a data structure that can efficiently insert elements (preserving their order) and check whether an element with the given Int key is already in the queue.

(==) :: StateQueue a -> StateQueue a -> Bool #

(/=) :: StateQueue a -> StateQueue a -> Bool #

Show a => Show (StateQueue a) Source # 
Instance details

Defined in Text.Regex.Applicative.StateQueue

empty :: StateQueue a Source #

The empty state queue

insert :: a -> StateQueue a -> StateQueue a Source #

Insert an element in the state queue without a key.

Since insert doesn't take a key, it won't affect any insertUnique.

insertUnique Source #

Arguments

:: Int

key

-> a 
-> StateQueue a 
-> StateQueue a 

Insert an element in the state queue, unless there is already an element with the same key

getElements :: StateQueue a -> [a] Source #

Get the list of all elements
