A builder to configure download request.

See custom configuration for an example.

Implementations

impl<'a> RequestBuilder<'a>

pub fn hash<D: DynDigest + 'static>(self, expected: &str, digest: D) -> Self

Sets expected file hash and digest used to calculate it.

Hash is given in hexadecimal, uppercase or lowercase.

Examples

use ml_downloader::Downloader;
use sha2::{Digest, Sha256};

let mut downloader = Downloader::new()?;
let bytes = downloader
    .get("https://example.com/")
    .hash("e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855", Sha256::new())
    .send()?;

pub fn send(self) -> Result<Bytes, Error>

Creates download request and sends it to target URL, with retries.

• Sleeps before starting download if needed.
  • See DownloaderBuilder::interval and Downloader::sleep_until_ready.
• Number of retries and the delays inbetween them is configured with DownloaderBuilder::retry_delays.

See simple usage and RequestBuilder::hash for examples.
