Struct SectorBitSet 

pub struct SectorBitSet { /* private fields */ }

A simple bitset for tracking sector states.

Used to track which sectors have been written and which have faults. Implements a compact representation using u64 words.

Implementations

impl SectorBitSet

pub fn new(num_sectors: usize) -> Self

Create a new bitset with capacity for the given number of sectors.

All bits are initially unset (false).

pub fn set(&mut self, sector: usize)

Set the bit for the given sector.

Panics

Panics if sector is out of bounds.

pub fn clear(&mut self, sector: usize)

Clear the bit for the given sector.

Panics

Panics if sector is out of bounds.

pub fn is_set(&self, sector: usize) -> bool

Check if the bit for the given sector is set.

Panics

Panics if sector is out of bounds.

pub fn len(&self) -> usize

Return the number of sectors this bitset can track.

pub fn is_empty(&self) -> bool

Check if the bitset is empty (has zero capacity).

pub fn resize_copy(other: &Self, new_len: usize) -> Self

Create a new bitset by copying set bits from another bitset.

Only copies bits up to the minimum of both bitsets’ lengths.

Trait Implementations

impl Clone for SectorBitSet

fn clone(&self) -> SectorBitSet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SectorBitSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
