Trait Implementations

impl<'a> TerminalReader<MemoryTerminal> for MemoryReadGuard<'a>

fn wait_for_input(&mut self, _timeout: Option<Duration>) -> Result<bool>

Waits timeout for user input. If timeout is None, waits indefinitely.

fn prepare(
    &mut self,
    _block_signals: bool,
    _report_signals: SignalSet
) -> Result<()>

Prepares the terminal for line reading and editing operations.

unsafe fn prepare_with_lock(
    &mut self,
    _lock: &mut dyn TerminalWriter<MemoryTerminal>,
    _block_signals: bool,
    _report_signals: SignalSet
) -> Result<()>

Like prepare, but called when the write lock is already held.

fn restore(&mut self, _state: ()) -> Result<()>

Restores the terminal state using the given state data.

unsafe fn restore_with_lock(
    &mut self,
    _lock: &mut dyn TerminalWriter<MemoryTerminal>,
    _state: ()
) -> Result<()>

Like restore, but called when the write lock is already held.

fn read(&mut self, buf: &mut Vec<u8>) -> Result<RawRead>

Reads some input from the terminal and appends it to the given buffer.
