Struct ring::io::Positive

source · 
pub struct Positive<'a>(/* private fields */);
Expand description

A serialized positive integer.

Implementations§

source§

impl<'a> Positive<'a>

source

pub fn big_endian_without_leading_zero(&self) -> &'a [u8] ⓘ

Returns the value, ordered from significant byte to least significant byte, without any leading zeros. The result is guaranteed to be non-empty.

source§

impl Positive<'_>

source

pub fn first_byte(&self) -> u8

Returns the first byte.

Will not panic because the value is guaranteed to have at least one byte.
