Implementors

impl AppState for BrowserState[src]

fn do_pending_task(&mut self, screen: &mut Screen, dam: &mut Dam)[src]

do some work, totally or partially, if there's some to do. Stop as soon as the dam asks for interruption

fn write_flags(
    &self,
    w: &mut dyn Write,
    screen: &mut Screen,
    _con: &AppContext
) -> Result<(), ProgramError>[src]

draw the flags at the bottom right of the screen

impl AppState for HelpState[src]

fn write_flags(
    &self,
    w: &mut dyn Write,
    screen: &mut Screen,
    _con: &AppContext
) -> Result<(), ProgramError>[src]
