Struct ResumeState 

pub struct ResumeState { /* private fields */ }

On-disk resume state for one file.

Implementations

impl ResumeState

pub fn state_path(final_path: &Path) -> PathBuf

pub fn load_or_new(final_path: &Path, size: u64, chunk_size: u32) -> Self

Load existing state, or start empty.

Any mismatch — different size, different chunk size, a truncated or corrupt file — is treated as “no state”, which costs a retransfer and never risks a corrupt result.

pub fn bitmap(&self) -> &ChunkBitmap

pub fn has(&self, chunk: u64) -> bool

pub fn record(&mut self, chunk: u64)

Record a chunk as written but not yet durable.

pub fn pending(&self) -> u64

pub fn is_complete(&self) -> bool

pub fn checkpoint(&mut self, handle: &WriteHandle) -> Result<()>

Flush data, then persist the bitmap. Never the other way round.

pub fn clear(&self)

Remove the state file once the transfer is committed.
