rustHow to convert a u8 slice to a hex string in Rust?

To convert a u8 slice to a hex string in Rust, you can use the format! macro. The {:x} format specifier is used to convert the u8 slice to a hex string.

Example code

let bytes = [0x41, 0x42, 0x43];
let hex_string = format!("{:x}", bytes);

Output example

"414243"

Code explanation

• let bytes = [0x41, 0x42, 0x43];: This line declares a u8 slice with the values 0x41, 0x42, and 0x43.
• let hex_string = format!("{:x}", bytes);: This line uses the format! macro to convert the u8 slice to a hex string. The {:x} format specifier is used to convert the u8 slice to a hex string.
