Trait tract_pulse::internal::fmt::UpperHex

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

X formatting.

The UpperHex trait should format its output as a number in hexadecimal, with A through F in upper case.

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

The alternate flag, #, adds a 0x 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 '2A' in hex

assert_eq!(format!("{:X}", x), "2A");
assert_eq!(format!("{:#X}", x), "0x2A");

assert_eq!(format!("{:X}", -16), "FFFFFFF0");

Implementing UpperHex on a type:

use std::fmt;

struct Length(i32);

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

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

let l = Length(i32::MAX);

assert_eq!(format!("l as hex is: {:X}", l), "l as hex is: 7FFFFFFF");

assert_eq!(format!("l as hex is: {:#010X}", l), "l as hex is: 0x7FFFFFFF");

Required methods

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

Render the contents of a BitSlice in a numeric format.

These implementations render the bits of memory contained in a BitSlice as one of the three numeric bases that the Rust format system supports:

• Binary renders each bit individually as 0 or 1,
• Octal renders clusters of three bits as the numbers 0 through 7,
• and UpperHex and LowerHex render clusters of four bits as the numbers 0 through 9 and A through F.

The formatters produce a “word” for each element T of memory. The chunked formats (octal and hexadecimal) operate somewhat peculiarly: they show the semantic value of the memory, as interpreted by the ordering parameter’s implementation rather than the raw value of memory you might observe with a debugger. In order to ease the process of expanding numbers back into bits, each digit is grouped to the right edge of the memory element. So, for example, the byte 0xFF would be rendered in as 0o377 rather than 0o773.

Rendered words are chunked by memory elements, rather than by as clean as possible a number of digits, in order to aid visualization of the slice’s place in memory.
