Function replay 

pub fn replay<I, F, R>(
    harness: &mut F,
    replay_cfg: &ReplayOptions,
) -> Result<(), Box<dyn Error>>
where
    I: Input,
    F: FnMut(&I) -> R,

Replay inputs from files using the provided harness function.

Arguments

• harness - A mutable function that accepts a BytesInput reference and produces some result.
• replay_cfg - Configuration options for the replay process.

Returns

Ok(()) if all files were replayed successfully, or an Error if any file operations fail.

Description

This function iterates through a list of files specified in the replay configuration, reads each file’s contents, converts them to BytesInput objects, and passes them to the provided harness function. It respects the start and end indices in the configuration and provides progress updates every 100 files processed.
