pub struct Downloader { /* private fields */ }

Implementations

impl Downloader

pub fn get_client(&self) -> &Client

pub fn get_url(&self) -> String

pub fn get_len(&self) -> u64

pub fn filename(&self) -> &str

pub fn new_manual(url: &str, workers: u8, length: u64) -> Result<Self>

pub fn new(url: &str, workers: u8) -> Result<Self>

Create a new downloader

Arguments

• url - URL of the file
• workers - amount of concurrent tasks

Examples

use manic::threaded::Downloader;
   let downloader = Downloader::new("https://crates.io", 5)?;

pub fn url_to_filename(url: &Url) -> Result<String>

pub fn progress_bar(&mut self) -> &mut Self

Enable progress reporting

pub fn connect_progress(&mut self, pb: ProgressBar)

Connect the ProgressBarindicatif::ProgressBar to the MultiProgressindicatif::MultiProgress

pub fn bar_style(&self, style: ProgressStyle)

Set the progress bar style

pub fn verify(&mut self, hash: Hash) -> Self

Add a SHA checksum to verify against

Arguments

• hash - Hash to verify against

pub fn download(&self) -> Result<ChunkVec>

Download the file and verify if hash is set

Example

use manic::threaded::Downloader;
use manic::ManicError;
let client = Downloader::new("https://crates.io", 5)?;
let result = client.download()?;

pub fn multi_download(self) -> Result<Downloaded>

pub fn download_and_save(&self, path: &str) -> Result<()>

Used to download, save to a file and verify against a SHA256 sum, returns an error if the connection fails or if the sum doesn’t match the one provided

Arguments

• path - path to save the file to, if it’s a directory then the original filename is used
• verify - set true to verify the file against the hash

Example

use manic::threaded::Downloader;
use manic::ManicError;
use manic::Hash;
fn main() -> Result<(), ManicError> {
    let hash = Hash::new_sha256("039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81".to_string());
    let client = Downloader::new("https://crates.io", 5)?.verify(hash);
    client.download_and_save("~/Downloads")?;
    Ok(())
 }
