Module arrow2::bitmap

contains Bitmap and MutableBitmap, containers of bool.

Modules

utils

General utilities for bitmaps representing items where LSB is the first item.

Structs

Bitmap

An immutable container whose API is optimized to handle bitmaps. All quantities on this container’s API are measured in bits.

MutableBitmap

A container to store booleans. MutableBitmap is semantically equivalent to Vec<bool>, but each value is stored as a single bit, thereby achieving a compression of 8x. This container is the counterpart of Vec for boolean values. MutableBitmap can be converted to a Bitmap at O(1). The main difference against Vec<bool> is that a bitmap cannot be represented as &[bool].

Functions

binary

Apply a bitwise operation op to two inputs and return the result as a Bitmap.

chunk_iter_to_vec

Creates a Vec<u8> from a TrustedLen of BitChunk.

from_chunk_iter_unchecked^⚠

Creates a Vec from an Iterator of BitChunk.

quaternary

Apply a bitwise operation op to four inputs and return the result as a Bitmap.

ternary

Apply a bitwise operation op to three inputs and return the result as a Bitmap.

unary

Apply a bitwise operation op to one input and return the result as a Bitmap.
