Trait nom::lib::std::fmt::Octal1.0.0[−][src]

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

o formatting.

The Octal trait should format its output as a number in base-8.

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

The alternate flag, #, adds a 0o 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 '52' in octal

assert_eq!(format!("{:o}", x), "52");
assert_eq!(format!("{:#o}", x), "0o52");

assert_eq!(format!("{:o}", -16), "37777777760");

Implementing Octal on a type:

use std::fmt;

struct Length(i32);

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

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

let l = Length(9);

assert_eq!(format!("l as octal is: {:o}", l), "l as octal is: 11");

assert_eq!(format!("l as octal is: {:#06o}", l), "l as octal is: 0o0011");

Required methods

`pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>`[src][−]
