BtBencode
BtBencode is a library which can help with Bencode encoding/decoding. Bencode is primarily used in BitTorrent related applications.
It uses the Serde library to serialize and deserialize Bencode data. It is similar to Serde JSON in terms of functionality and implementation.

Examples
An example serializing a standard Rust collection type and then deserializing into a custom type:
use std::collections::BTreeMap;
use serde_derive::Deserialize;
let mut dict: BTreeMap<String, String> = BTreeMap::new();
dict.insert(String::from("url"), String::from("https://example.com/"));
let serialized_bytes = bt_bencode::to_vec(&dict)?;
#[derive(Deserialize)]
struct Info<'a> {
url: &'a str,
}
let info: Info = bt_bencode::from_slice(&serialized_bytes)?;
assert_eq!(info.url, "https://example.com/");
An example deserializing from a slice of bytes into a general Value
representation and then from the Value
instance into a more strongly typed
data structure.
use serde_derive::{Serialize, Deserialize};
use bt_bencode::Value;
#[derive(Serialize, Deserialize)]
struct Info {
t: String,
url: String,
}
let serialized_bytes = bt_bencode::to_vec(&Info {
t: String::from("query"),
url: String::from("https://example.com/"),
})?;
let value: Value = bt_bencode::from_slice(&serialized_bytes)?;
assert_eq!(value["t"].as_str().unwrap(), "query");
assert_eq!(
value.get("url").and_then(|url| url.as_str()).unwrap(),
"https://example.com/"
);
let info: Info = bt_bencode::from_value(value)?;
assert_eq!(info.t, "query");
assert_eq!(info.url, "https://example.com/");
