Module display

Helpers for displaying bytes as hex strings.

This module provides a trait for displaying things as hex as well as an implementation for &[u8].

For arrays and slices we support padding and precision for length < 512 bytes.

Examples

use hex_conservative::DisplayHex;

// Display as hex.
let v = vec![0xde, 0xad, 0xbe, 0xef];
assert_eq!(format!("{}", v.as_hex()), "deadbeef");

// Get the most significant bytes.
let v = vec![0x01, 0x23, 0x45, 0x67];
assert_eq!(format!("{0:.4}", v.as_hex()), "0123");

// Padding with zeros
let v = vec![0xab; 2];
assert_eq!(format!("{:0>8}", v.as_hex()), "0000abab");

Macros

• fmt_hex_exact
  Format known-length array as hex.
• impl_fmt_traits
  Adds core::fmt trait implementations to type $ty.

Structs

• DisplayArray
  Displays byte array as hex.
• DisplayByteSlice
  Displays byte slice as hex.
• HexWritertest or std
  Given a T: fmt::Write, HexWriter implements std::io::Write and writes the source bytes to its inner T as hex characters.

Traits

• DisplayHex
  Extension trait for types that can be displayed as hex.
