Struct Metainfo

pub struct Metainfo { /* private fields */ }

Metainfo file (also known as .torrent; see BEP3) describe all data required to find download file/files from peer-to-peer network.

Implementations

impl Metainfo

pub fn create_file(path: &Path, tracker_addr: &String) -> Result<(), Error>

Create new torrent file.

Example

use rdest::Metainfo;
use std::path::Path;

Metainfo::create_file(Path::new("my_file.dat"), &"http://127.0.0.1:8000".to_string()).unwrap();

pub fn from_file(path: &Path) -> Result<Metainfo, Error>

Read metainfo (.torrent) data from file.

Example

use rdest::Metainfo;
use std::path::PathBuf;

let path = PathBuf::from("ubuntu-20.04.2.0-desktop-amd64.iso.torrent");
let torrent = Metainfo::from_file(path.as_path()).unwrap();

pub fn from_bencode(data: &[u8]) -> Result<Metainfo, Error>

Read metainfo (.torrent) data directly from bencoded string.

Example

use rdest::Metainfo;

let torrent = Metainfo::from_bencode(b"d8:announce3:URL4:infod4:name4:NAME12:piece lengthi111e6:pieces20:AAAAABBBBBCCCCCDDDDD6:lengthi222eee").unwrap();

pub fn find_announce(dict: &HashMap<Vec<u8>, BValue>) -> Result<String, Error>

Find value for “announce” key in pre-parsed dictionary (converted to HashMap).

pub fn find_name(dict: &HashMap<Vec<u8>, BValue>) -> Result<String, Error>

Find value for “info:name” key in pre-parsed dictionary (converted to HashMap).

pub fn find_piece_length(dict: &HashMap<Vec<u8>, BValue>) -> Result<u64, Error>

Find value for “info:piece length” key in pre-parsed dictionary (converted to HashMap).

pub fn find_pieces( dict: &HashMap<Vec<u8>, BValue>, ) -> Result<Vec<[u8; 20]>, Error>

Find value for “info:pieces” key in pre-parsed dictionary (converted to HashMap).

pub fn find_length(dict: &HashMap<Vec<u8>, BValue>) -> Option<u64>

Find value for “info:length” key in pre-parsed dictionary (converted to HashMap).

pub fn find_files(dict: &HashMap<Vec<u8>, BValue>) -> Option<Vec<File>>

Find value for “info:files” key in pre-parsed dictionary (converted to HashMap).

pub fn tracker_url(&self) -> &String

Return URL of the tracker

pub fn piece(&self, piece_index: usize) -> &[u8; 20]

Return SHA-1 hash of specific piece.

pub fn pieces_num(&self) -> usize

Return number of SHA-1 hashes.

pub fn piece_length(&self, piece_index: usize) -> usize

Return length of specific piece.

pub fn total_length(&self) -> u64

Return length of all files described by torrent.

pub fn info_hash(&self) -> &[u8; 20]

Return SHA-1 hash of info section.

pub fn file_piece_ranges(&self) -> Vec<(PathBuf, PiecePos, PiecePos)>

Return vector with information which pieces contain which files.

Trait Implementations

impl Clone for Metainfo

fn clone(&self) -> Metainfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Metainfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Metainfo

fn eq(&self, other: &Metainfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
