Struct BNumber

pub struct BNumber { /* private fields */ }

Struct for representing numbers in Bencode format.

Implementations

impl BNumber

pub fn new(number: i64) -> BNumber

Simple constructor from one i64.

Trait Implementations

impl BElement<BNumber> for BNumber

fn decode(encoded: &[u8]) -> Result<(usize, BNumber), &'static str>

Decodes BNumber from array of bytes.

Returnes Ok((position of last used byte in passed array, parsed BNumber)) or Err if couldn’t parse BNumber correctly.

Examples

BNumber must begin with ‘i’ char and end with ‘e’ char.

use bencode_decoder::BElement;
use bencode_decoder::BNumber;
assert_eq!((4, BNumber::new(300)),
               BNumber::decode("i300e".as_bytes()).ok().expect("invalid"));
assert_eq!((5, BNumber::new(-204)),
               BNumber::decode("i-204e".as_bytes()).ok().expect("invalid"));

If it’s not, then error is generated.

use bencode_decoder::BElement;
use bencode_decoder::BNumber;
assert!(BNumber::decode("l300e".as_bytes()).is_err());

Also error is generated, when number isn’t valid or is too big for i64.

use bencode_decoder::BElement;
use bencode_decoder::BNumber;
assert!(BNumber::decode("i400000000000000000000000000000000000000000000e".as_bytes()).is_err());

impl Debug for BNumber

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

Formats the value using the given formatter.

impl PartialEq for BNumber

fn eq(&self, other: &BNumber) -> 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.
