Implementations

impl Sign

pub fn try_from(byte: u8) -> Option<Sign>

Trys to convert an ascii character into a Sign

Example

use atoi::Sign;
assert_eq!(Some(Sign::Plus), Sign::try_from(b'+'));
assert_eq!(Some(Sign::Minus), Sign::try_from(b'-'));
assert_eq!(None, Sign::try_from(b'1'));

pub fn signum<I>(self) -> I

where I: Signed,

Returns either +1 or -1

Trait Implementations

impl Clone for Sign

fn clone(&self) -> Sign

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sign

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

Formats the value using the given formatter.

impl PartialEq for Sign

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