    bytes: &[u8],
    group: usize,
    max_lines: Option<usize>,
) -> FixedStr<N>
Expand description

Formats the given byte slice as an uppercase hexadecimal string, grouping bytes as specified and inserting spaces and newlines accordingly, then returns a FixedStr containing the formatted output. Any unused space in the output buffer is zero‑padded.

§Parameters

  • bytes: The input byte slice to format.
  • group: The number of bytes per group. A newline is inserted when a group is complete.
  • max_lines: An optional limit to the number of output lines. If None, all groups are printed.

§Returns

A FixedStr containing the hex‑formatted representation of bytes.

§Panics

Panics if group == 0.
