Function dedupe_folder 

pub(crate) fn dedupe_folder(
    channel_dir: &Path,
    rotate_secs: u64,
    dry_run: bool,
) -> Result<Outcome>

See the module documentation for the steps. The original folder is only replaced after the staged copy has passed both checks; on any error the staging folder is deleted and the original is left as it was.

Arguments

• channel_dir - The ch<NN> folder to process.
• rotate_secs - Window length in seconds.
• dry_run - When true, build and verify the new folder, then delete it.

Errors

Returns an error if a file cannot be read or written, a check fails, or the swap fails.
