# Documentation

appendVector :: Unboxed a => Vector a -> a -> IO () Source #

Add the specified element to the end of the vector.

readVector :: Unboxed a => Vector a -> Int -> IO a Source #

Read a value from the vector, where indices are started from 0.

writeVector :: Unboxed a => Vector a -> Int -> a -> IO () Source #

Set an array item at the specified index which is started from 0.

vectorBinarySearch :: (Unboxed a, Ord a) => Vector a -> a -> IO Int Source #

Return the index of the specified element using binary search; otherwise, a negated insertion index minus one: 0 -> -0 - 1, ..., i -> -i - 1, ....

vectorInsert :: Unboxed a => Vector a -> Int -> a -> IO () Source #

Insert the element in the vector at the specified index.

vectorDeleteAt :: Unboxed a => Vector a -> Int -> IO () Source #

Delete the element at the specified index.

:: Unboxed a | |

=> Vector a | the vector |

-> Int | the start index |

-> Int | the count of items to be removed |

-> IO () |

Delete the specified range of elements.

vectorDelete :: (Unboxed a, Eq a) => Vector a -> a -> IO Bool Source #

Remove the specified element and return a flag indicating whether the element was found and removed.

vectorDeleteBy :: Unboxed a => Vector a -> (a -> Bool) -> IO Bool Source #

Remove an element by the specified predicate and return a flag indicating whether the element was found and removed.

vectorIndex :: (Unboxed a, Eq a) => Vector a -> a -> IO Int Source #

Return the index of the item or -1.

vectorIndexBy :: Unboxed a => Vector a -> (a -> Bool) -> IO Int Source #

Return an index of the item satisfying the predicate or -1.

vectorContains :: (Unboxed a, Eq a) => Vector a -> a -> IO Bool Source #

Detect whether the specified element is contained in the vector.
