Struct BlockSet 

pub struct BlockSet { /* private fields */ }

A compact bitset tracking which blocks the receiver has verified good.

Used identically by the upload receiver (server) and the download receiver (client) so both directions share the same “mark good / mark bad / ask for missing” logic.

Implementations

impl BlockSet

pub fn new(total: u32) -> Self

A fresh, empty set covering total blocks.

pub fn insert(&mut self, index: u32)

Mark index as verified.

pub fn contains(&self, index: u32) -> bool

Whether index has been verified.

pub fn count(&self) -> u32

Number of verified blocks.

pub fn total(&self) -> u32

Total blocks this set covers.

pub fn missing(&self) -> Vec<u32>

All indices still not verified, in ascending order.

pub fn seed_from_ranges(&mut self, block_size: u64, ranges: &[(u64, u64)])

Seed from previously-received byte ranges (resume): every block overlapping [start, end) is marked verified.

Trait Implementations

impl Clone for BlockSet

fn clone(&self) -> BlockSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockSet

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

Formats the value using the given formatter.

impl Default for BlockSet

fn default() -> BlockSet

Returns the “default value” for a type.
