mini-io-queue's Issues

panic created in ring.rs

Not sure how this issue happens but I got a panic in ring.rs.
I'm running this crate with embassy to create an actor framework on a tm4c123 micro controller.
Panic ->

panicked at /home/lieven/.cargo/registry/src/index.crates.io-6f17d22bba15001f/mini-io-queue-0.2.0/src/ring.rs:136:9:
len was larger than left region length

The code of the read side , running within a with_timeout of embassy..

    async fn recv(&mut self) -> CMD {
        let mut cmd = [CMD::default()];
    //    let cnt = self.cmds_reader.read(&mut cmd).await;
        let r = self.cmds_reader.read_exact(&mut cmd).await;
        if r.is_err() {
            warn!("recv error {:?}", r);
        } else {
        }
 //       self.cmds_reader.consume(cnt);
        cmd[0].clone()
    }

The writer is doing a block_on execution.

    fn on(&mut self, cmd: &CMD) {
        let buf = [cmd.clone()];
        if block_on(self.cmds_writer.write(&buf)) == 0 {
            warn!(" cannot write command ")
        };
    }

Any suggestion , to find the root cause ?
