Function handle_next 

fn handle_next(
    _args: &Next,
    main_epoch: &mut EpochConfig,
) -> Result<(), AppError>

Handle the next sub-command.

Advances the epoch to the next scheduled event. If the current configuration contains any epochs with an identifier larger than the current one, an error is returned - otherwise the next epoch is computed.

Arguments

• main_epoch - mutable reference to the current EpochConfig (the cli_epoch::Next argument is unused).

Returns

• Ok(()) if the next epoch was successfully computed.
• Err(AppError::Epoch(EpochError::FutureEpochExist)) if there are no future epochs to advance to.
