Struct WriteLock

pub struct WriteLock<'a, B = Blocking> { /* private fields */ }

A lock for the write parts of a serial port. The read and write parts of this port state are described in the documentation for this module.

Implementations

impl<'a> WriteLock<'a>

pub fn set_non_blocking(self) -> WriteLock<'a, Nonblocking>

impl<B> WriteLock<'_, B>

pub fn set_baud_rate(&mut self, baud: usize) -> Result<()>

Set the serial port’s baud rate for this Lock.

When the Lock is dropped, the baud rate will be set to the previous value.

Errors

This returns an InvalidInput error if the target baud rate exceeds the maximum (115200), if the maximum baud rate is not divisible by the target, or if the target is so low that the resulting baud rate divisor is greater than u16::MAX (pretty unlikely!).

Trait Implementations

impl Write for WriteLock<'_, Blocking>

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

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Write.

impl Write for WriteLock<'_, Blocking>

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.

impl Write for WriteLock<'_, Nonblocking>

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

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Write.
