Struct rtt_target::UpChannel

pub struct UpChannel(_);

RTT up (target to host) channel

Supports writing binary data directly, or writing strings via core::fmt macros such as write as well as the ufmt crate's uwrite macros (use the u method).

Note that the formatted writing implementations diverge slightly from the trait definitions in that if the channel is in non-blocking mode, writing will not block.

Methods

impl UpChannel

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

Writes buf to the channel and returns the number of bytes written. Behavior when the buffer is full is subject to the channel blocking mode.

pub fn u(&mut self) -> uWriter

Creates a writer for formatted writing with ufmt.

The correct way to use this method is to call it once for each write operation. This is so that non blocking modes will work correctly.

let mut output = channels.up.0;
uwriteln!(output.u(), "Hello, ufmt!");

pub fn mode(&self) -> ChannelMode

Gets the current blocking mode of the channel. The default is NoBlockSkip.

pub fn set_mode(&mut self, mode: ChannelMode)

Sets the blocking mode of the channel

pub fn into_terminal(self) -> TerminalChannel

Converts the channel into a virtual terminal that can be used for writing into multiple virtual terminals.

Trait Implementations

impl Send for UpChannel

impl Write for UpChannel

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

Writes a string slice 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.

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

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