Function fixed_buffer::escape_ascii

pub fn escape_ascii(input: &[u8]) -> String

Convert a byte slice into a string. Includes printable ASCII characters as-is. Converts non-printable or non-ASCII characters to strings like "\n" and "\x19".

Uses core::ascii::escape_default internally to escape each byte.

This function is useful for printing byte slices to logs and comparing byte slices in tests.

Example test:

use fixed_buffer::escape_ascii;
assert_eq!("abc", escape_ascii(b"abc"));
assert_eq!("abc\\n", escape_ascii(b"abc\n"));
assert_eq!(
    "Euro sign: \\xe2\\x82\\xac",
    escape_ascii("Euro sign: \u{20AC}".as_bytes())
);
assert_eq!("\\x01\\x02\\x03", escape_ascii(&[1, 2, 3]));
