Function key_to_hex

Source 
pub fn key_to_hex<const N: usize>(key: DataRefType<'_, N>) -> Option<String>
Expand description

Converts a DataType array into a hexadecimal string.

This function takes a DataType array (key) and converts it into its corresponding hexadecimal string representation. If the key is None, it returns None.

§Type Parameters:

  • N: The size of the DataType array. This is a constant array length that ensures type safety.

§Arguments:

  • key: A reference to a DataType array of size N. This is the key to be encoded into a hexadecimal string. It must be a valid key array of the appropriate size.

§Returns:

  • Some(String): The hexadecimal string representation of the key if the key is Some. Returns None if the key is None.

§Example:

let key = Some([0xa1, 0xb2, 0xc3, 0xd4, 0xe5, 0xf6, 0x78, 0x90]);
let hexstr = key_to_hex(key);
assert_eq!(hexstr, Some("a1b2c3d4e5f67890".to_string()));
