Implementations

impl HttpDownloader

pub fn new(config: &EngineConfig) -> Result<Self>

Create a new HTTP downloader

pub fn retry_policy(&self) -> &RetryPolicy

Get the retry policy

pub async fn download<F>( &self, url: &str, save_dir: &Path, filename: Option<&str>, user_agent: Option<&str>, referer: Option<&str>, headers: &[(String, String)], cookies: Option<&[String]>, checksum: Option<&ExpectedChecksum>, cancel_token: CancellationToken, progress_callback: F, ) -> Result<PathBuf>

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

Download a file from a URL

Returns the final path of the downloaded file

pub async fn download_segmented<F>( &self, url: &str, save_dir: &Path, filename: Option<&str>, user_agent: Option<&str>, referer: Option<&str>, headers: &[(String, String)], cookies: Option<&[String]>, checksum: Option<&ExpectedChecksum>, max_connections: usize, min_segment_size: u64, cancel_token: CancellationToken, saved_segments: Option<Vec<Segment>>, progress_callback: F, segmented_ref: Option<Arc<RwLock<Option<Arc<SegmentedDownload>>>>>, ) -> Result<(PathBuf, Option<Arc<SegmentedDownload>>)>

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

Download a file using multiple connections (segmented download)

This method probes the server first and uses segmented downloads if the server supports Range requests and the file is large enough. Download with segmented multi-connection support.

Returns the final path and optionally an Arc reference to the SegmentedDownload (only when using segmented download mode).
