1.0.0[−][src]Trait skellige::prelude::fmt::Octal
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]
Formats the value using the given formatter.
