Struct blot::uvar::Uvar

pub struct Uvar(_);

Methods

impl Uvar

pub fn new(bytes: Vec<u8>) -> Uvar

Constructs a new uvar from a byte list. Use {Uvar::from_bytes} if you need a safe constructor.

pub fn to_bytes(self) -> Vec<u8>

Consumes the list of bytes.

use blot::uvar::Uvar;

assert_eq!(Uvar::from_bytes(&[0x12]).unwrap().to_bytes(), vec![0x12]);

pub fn from_bytes(buffer: &[u8]) -> Result<Uvar, UvarError>

Transforms a byte list into a uvar.

pub fn take(buffer: &[u8]) -> Result<(Uvar, &[u8]), UvarError>

Takes a uvar from a list of bytes and returns it with the rest of bytes.

use blot::uvar::Uvar;

let buffer = vec![0x12, 0x07, 0x06];
let (uvar, bytes) = Uvar::take(&buffer).unwrap();

assert_eq!(uvar, Uvar::from_bytes(&[0x12]).unwrap());
