[][src]Struct mio_serial::unix::Serial

pub struct Serial { /* fields omitted */ }

*nix serial port using termios

Methods

impl Serial[src]

pub fn from_path<T: AsRef<Path>>(
    path: T,
    settings: &SerialPortSettings
) -> Result<Self>
[src]

Open a nonblocking serial port from the provided path.

Example

This example is not tested
use std::path::Path;
use mio_serial::unix::Serial;
use mio_serial::SerialPortSettings;

let tty_name = Path::new("/dev/ttyUSB0");

let serial = Serial::from_path(tty_name, &SerialPortSettings::default()).unwrap();

pub fn from_serial(port: TTYPort) -> Result<Self>[src]

Convert an existing serialport::posix::TTYPort struct.

Example

This example is not tested
extern crate serialport;

use std::path::Path;
use serialport::posix::TTYPort;
use mio_serial::unix::Serial;

let tty_name = Path::new("/dev/ttyUSB0");
let blocking_serial = TTYPort::open(tty_path).unwrap();

let serial = Serial::from_serial(blocking_serial).unwrap();

pub fn pair() -> Result<(Self, Self)>[src]

Create a pair of pseudo serial terminals

Returns

Two connected Serial objects: (master, slave)

Errors

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

Examples

use mio_serial::unix::Serial;

let (master, slave) = Serial::pair().unwrap();

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

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[src]

Returns the exclusivity of the port

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

impl AsRawFd for Serial[src]

impl FromRawFd for Serial[src]

impl IntoRawFd for Serial[src]

impl Evented for Serial[src]

impl SerialPort for Serial[src]

fn settings(&self) -> SerialPortSettings[src]

Returns a struct with the current port settings

fn name(&self) -> Option<String>[src]

Return the name associated with the serial port, if known.

fn baud_rate(&self) -> Result<u32>[src]

Returns the current baud rate.

This function returns None if the baud rate could not be determined. This may occur if the hardware is in an uninitialized state. Setting a baud rate with set_baud_rate() should initialize the baud rate to a supported value.

fn data_bits(&self) -> Result<DataBits>[src]

Returns the character size.

This function returns None if the character size could not be determined. This may occur if the hardware is in an uninitialized state or is using a non-standard character size. Setting a baud rate with set_char_size() should initialize the character size to a supported value.

fn flow_control(&self) -> Result<FlowControl>[src]

Returns the flow control mode.

This function returns None if the flow control mode could not be determined. This may occur if the hardware is in an uninitialized state or is using an unsupported flow control mode. Setting a flow control mode with set_flow_control() should initialize the flow control mode to a supported value.

fn parity(&self) -> Result<Parity>[src]

Returns the parity-checking mode.

This function returns None if the parity mode could not be determined. This may occur if the hardware is in an uninitialized state or is using a non-standard parity mode. Setting a parity mode with set_parity() should initialize the parity mode to a supported value.

fn stop_bits(&self) -> Result<StopBits>[src]

Returns the number of stop bits.

This function returns None if the number of stop bits could not be determined. This may occur if the hardware is in an uninitialized state or is using an unsupported stop bit configuration. Setting the number of stop bits with set_stop-bits() should initialize the stop bits to a supported value.

fn timeout(&self) -> Duration[src]

Returns the current timeout. This parameter is const and equal to zero and implemented due to required for trait completeness.

fn set_all(&mut self, settings: &SerialPortSettings) -> Result<()>[src]

Applies all settings for a struct. This isn't guaranteed to involve only a single call into the driver, though that may be done on some platforms.

fn set_baud_rate(&mut self, baud_rate: u32) -> Result<()>[src]

Sets the baud rate.

Errors

If the implementation does not support the requested baud rate, this function may return an InvalidInput error. Even if the baud rate is accepted by set_baud_rate(), it may not be supported by the underlying hardware.

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

Sets the character size.

fn set_flow_control(&mut self, flow_control: FlowControl) -> Result<()>[src]

Sets the flow control mode.

fn set_parity(&mut self, parity: Parity) -> Result<()>[src]

Sets the parity-checking mode.

Sets the number of stop bits.

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

Sets the timeout for future I/O operations. This parameter is ignored but required for trait completeness.

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

Sets the state of the RTS (Request To Send) control signal.

Setting a value of true asserts the RTS control signal. false clears the signal.

Errors

This function returns an error if the RTS control signal could not be set to the desired state on the underlying hardware:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

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

Writes to the Data Terminal Ready pin

Setting a value of true asserts the DTR control signal. false clears the signal.

Errors

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

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

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

This function returns a boolean that indicates whether the CTS control signal is asserted.

Errors

This function returns an error if the state of the CTS control signal could not be read from the underlying hardware:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

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

Reads the state of the Data Set Ready control signal.

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

fn read_ring_indicator(&mut self) -> Result<bool>[src]

Reads the state of the Ring Indicator control signal.

This function returns a boolean that indicates whether the RI control signal is asserted.

Errors

This function returns an error if the state of the RI control signal could not be read from the underlying hardware:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

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

Reads the state of the Carrier Detect control signal.

This function returns a boolean that indicates whether the CD control signal is asserted.

Errors

This function returns an error if the state of the CD control signal could not be read from the underlying hardware:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

fn bytes_to_read(&self) -> Result<u32>[src]

Gets the number of bytes available to be read from the input buffer.

Errors

This function may return the following errors:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

fn bytes_to_write(&self) -> Result<u32>[src]

Get the number of bytes written to the output buffer, awaiting transmission.

Errors

This function may return the following errors:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

fn clear(&self, buffer_to_clear: ClearBuffer) -> Result<()>[src]

Discards all bytes from the serial driver's input buffer and/or output buffer.

Errors

This function may return the following errors:

  • NoDevice if the device was disconnected.
  • Io for any other type of I/O error.

fn try_clone(&self) -> Result<Box<dyn SerialPort>>[src]

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.

Also, you must be very carefull when changing the settings of a cloned SerialPort : since the settings are cached on a per object basis, trying to modify them from two different objects can cause some nasty behavior.

Errors

This function returns an error if the serial port couldn't be cloned.
