Struct Downloader 

pub struct Downloader { /* private fields */ }

A reusable HTTP downloader.

Implementations

impl Downloader

pub fn new() -> VtaResult<Downloader>

Build a downloader with sane defaults (TLS via rustls, connect timeout).

pub fn with_retries(self, retries: u32) -> Self

Override the per-URL retry count (default 3).

pub fn download(&self, url: &str, dest: &Path) -> VtaResult<()>

Download url into dest, resuming a partial <dest>.part if present and retrying transient failures with backoff.

pub fn download_any(&self, urls: &[String], dest: &Path) -> VtaResult<()>

Try a primary URL then mirrors/alternates in order, returning on the first success. A mirror that serves wrong bytes is caught by the caller’s hash verification, so falling through mirrors is safe (docs/13-offline.md).
