Examples

Example: converting string to hex

To convert a string to hex, use the Hex and Convert trait:

use hextool::{Hex, Convert};

// Convert a string to hex
let hex = Hex::convert("hello", false, false);
println!("hello in hex: {}", hex); // #=> "hello in hex: 68656c6c6f"

// You can also split the output in bytes
let hex = Hex::convert("hello", false, true);
println!("hello in hex: {}", hex); // #=> "hello in hex: 68 65 6c 6c 6f"

// Convert a string with numeric flag. This will take the numerical value of the string.
// If the string is not a number, it will return an error.
let hex = Hex::convert("255", true, false);
println!("255 in hex: {}", hex); // #=> "255 in hex: {ff}"

Example: converting hex to string

To convert a hex string to a string, use the UnHex and Convert trait:

use hextool::{UnHex, Convert};

// Convert a hex string to a string
let unhex = UnHex::convert("68656c6c6f", false, false);
println!("68656c6c6f in string: {}", unhex); // #=> "68656c6c6f in string: hello"

// Convert a hex string to a string with numeric flag. This will take the numerical value of the string.
let unhex = UnHex::convert("cafebabe", true, false);
println!("cafebabe in string: {}", unhex); // #=> "cafebabe in string: 3405691582"

// If numeric is set to false, only valid strings [0-9a-f] is accepted. If the string is not valid,
// it will return the string with the invalid string highlighted to red.
let unhex = UnHex::convert("aga", true, false);
println!("{}", unhex); // #=> "The highlighted chars can't be converted:\nag\u{1b}[31ma\u{1b}[0m."
