Implementations

impl SegmentedDownload

pub fn new( url: String, total_size: u64, save_path: PathBuf, supports_range: bool, etag: Option<String>, last_modified: Option<String>, ) -> Self

Create a new segmented download

pub fn init_segments(&mut self, max_connections: usize, min_segment_size: u64)

Initialize segments for a new download

pub fn restore_segments(&mut self, saved_segments: Vec<Segment>)

Restore segments from saved state

pub fn segments(&self) -> &[Segment]

Get current segments

pub fn segments_with_progress(&self) -> Vec<Segment>

Get segments with current progress updated

This creates a snapshot of the current segment state for persistence.

pub async fn start<F>( &self, client: &Client, user_agent: &str, headers: &[(String, String)], max_connections: usize, cancel_token: CancellationToken, progress_callback: F, ) -> Result<()>

where F: Fn(DownloadProgress) + Send + Sync + 'static,

Start the segmented download

pub fn should_persist(&self) -> bool

Check if persistence is due based on the time interval.

Returns true if enough time has passed since the last persistence, and resets the timer if so.

pub fn mark_persisted(&self)

Force mark persistence as done (call after successful save).

pub fn pause(&self)

Pause the download

pub fn is_complete(&self) -> bool

Check if download is complete

pub fn progress(&self) -> DownloadProgress

Get current progress
