Struct tokio_serial::Serial

pub struct Serial { /* fields omitted */ }

Serial port I/O struct.

Methods

impl Serial

pub fn from_path<P>(path: P, settings: &SerialPortSettings) -> Result<Serial> where     P: AsRef<Path>,

Open serial port from a provided path, using the default reactor.

pub fn from_path_with_handle<P>(     path: P,     settings: &SerialPortSettings,     handle: &Handle ) -> Result<Serial> where     P: AsRef<Path>,

Open serial port from a provided path, using the specified reactor.

pub fn pair() -> Result<(Self, Self)>

Create a pair of pseudo serial terminals using the default reactor

Returns

Two connected, unnamed Serial objects.

Errors

Attempting any IO or parameter settings on the slave tty after the master tty is closed will return errors.

pub fn pair_with_handle(handle: &Handle) -> Result<(Self, Self)>

Create a pair of pseudo serial terminals using the specified reactor.

Returns

Two connected, unnamed Serial objects.

Errors

Attempting any IO or parameter settings on the slave tty after the master tty is closed will return errors.

pub fn set_exclusive(&mut self, exclusive: bool) -> Result<()>

Sets the exclusivity of the port

If a port is exclusive, then trying to open the same device path again will fail.

See the man pages for the tiocexcl and tiocnxcl ioctl's for more details.

Errors

• Io for any error while setting exclusivity for the port.

pub fn exclusive(&self) -> bool

Returns the exclusivity of the port

If a port is exclusive, then trying to open the same device path again will fail.

Trait Implementations

impl SerialPort for Serial

Sets the baud rate.

fn set_data_bits(&mut self, data_bits: DataBits) -> Result<()>

Sets the character size.

Sets the parity-checking mode.

fn set_stop_bits(&mut self, stop_bits: StopBits) -> Result<()>

Sets the number of stop bits.

fn set_timeout(&mut self, _: Duration) -> Result<()>

Sets the timeout for future I/O operations.

fn write_request_to_send(&mut self, level: bool) -> Result<()>

fn write_data_terminal_ready(&mut self, level: bool) -> Result<()>

Writes to the Data Terminal Ready pin

fn read_clear_to_send(&mut self) -> Result<bool>

Reads the state of the CTS (Clear To Send) control signal.

fn read_data_set_ready(&mut self) -> Result<bool>

Reads the state of the Data Set Ready control signal.

Reads the state of the Ring Indicator control signal.

fn read_carrier_detect(&mut self) -> Result<bool>

Reads the state of the Carrier Detect control signal.

fn try_clone(&self) -> Result<Box<SerialPort>>

Attempts to clone the SerialPort. This allow you to write and read simultaneously from the same serial connection. Please note that if you want a real asynchronous serial port you should look at mio-serial or tokio-serial.

impl Read for Serial

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.
