Trait nom::lib::std::fmt::Binary

pub trait Binary {
    pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>;
}

[−] Expand description

b formatting.

The Binary trait should format its output as a number in binary.

For primitive signed integers (i8 to [i128], and isize), negative values are formatted as the two’s complement representation.

The alternate flag, #, adds a 0b in front of the output.

For more information on formatters, see the module-level documentation.

Examples

Basic usage with [i32]:

let x = 42; // 42 is '101010' in binary

assert_eq!(format!("{:b}", x), "101010");
assert_eq!(format!("{:#b}", x), "0b101010");

assert_eq!(format!("{:b}", -16), "11111111111111111111111111110000");

Implementing Binary on a type:

use std::fmt;

struct Length(i32);

impl fmt::Binary for Length {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        let val = self.0;

        fmt::Binary::fmt(&val, f) // delegate to i32's implementation
    }
}

let l = Length(107);

assert_eq!(format!("l as binary is: {:b}", l), "l as binary is: 1101011");

assert_eq!(
    format!("l as binary is: {:#032b}", l),
    "l as binary is: 0b000000000000000000000001101011"
);

Required methods
