Module bitmap 

Bitmap utilities for Unix-like filesystems.

Provides efficient bit-level operations on block and inode bitmaps. Uses little-endian bit order within each byte (bit 0 = LSB), matching the standard Linux bitmap convention used by ext2/3/4, xfs AG bitmaps, UFS cylinder group bitmaps, and Minix zone maps.

Structs

BitmapReader

A read-only view over a bitmap stored as a byte slice.

ClearBitsIter

Iterator over clear bit indices in a BitmapReader.

SetBitsIter

Iterator over set bit indices in a BitmapReader.

Functions

bitmap_clear_bit

Clear the bit at index in a mutable bitmap (little-endian bit order).

bitmap_find_clear_bit

Find the first clear (0) bit in the bitmap within bit_count valid bits.

bitmap_set_bit

Set the bit at index in a mutable bitmap (little-endian bit order).
