Array

Namespace: Deedle.Internal

This module contains additional functions for working with arrays. Deedle.Internals is opened, it extends the standard Array module.

Functions and values

Function or value	Description
`binarySearchNearestGreater (...)` Signature: key:'T -> comparer:IComparer<'T> -> inclusive:bool -> array:ReadOnlyCollection<'T> -> int option Type parameters: 'T	Returns the index of 'key' or the index of immediately following value. If the specified key is greater than all keys in the array, None is returned. When 'inclusive' is false, the function returns the index of strictry greater value. Note that the function expects that the array contains distinct values (which is fine because LinearIndex does not support duplicate keys)
`binarySearchNearestSmaller (...)` Signature: key:'T -> comparer:IComparer<'T> -> inclusive:bool -> array:ReadOnlyCollection<'T> -> int option Type parameters: 'T	Returns the index of 'key' or the index of immediately preceeding value. If the specified key is smaller than all keys in the array, None is returned. When 'inclusive' is false, the function returns the index of strictry smaller value. Note that the function expects that the array contains distinct values (which is fine because LinearIndex does not support duplicate keys)
`choosei f array` Signature: f:(int -> '?495653 -> '?495654 option) -> array:'?495653 [] -> '?495654 [] Type parameters: '?495653, '?495654	Returns a new array containing only the elements for which the specified function returns `Some`. The predicate is called with the index in the source array and the element.
`dropRange first last data` Signature: first:int -> last:int -> data:'T [] -> 'T [] Type parameters: 'T	Drop a specified range from a given array. The operation is inclusive on both sides. Given [ 1; 2; 3; 4 ] and indices (1, 2), the result is [ 1; 4 ]
