Struct probe_rs_rtt::DownChannel

pub struct DownChannel(_);

RTT down (host to target) channel.

Implementations

impl DownChannel

pub fn number(&self) -> usize

Returns the number of the channel.

pub fn name(&self) -> Option<&str>

Returns the name of the channel or None if there is none.

pub fn buffer_size(&self) -> usize

Returns the buffer size in bytes. Note that the usable size is one byte less due to how the ring buffer is implemented.

pub fn write(&self, core: &mut Core<'_>, buf: &[u8]) -> Result<usize, Error>

Writes some bytes into the channel buffer and returns the number of bytes written.

This method will not block waiting for space to become available in the channel buffer, and may not write all of buf.
