[Error] Method not found in SampleMut

[antaradey-itk]

Hello.

I am new to Rust, and currently working on a project of Rust Posix interoperability. I am trying to explore ways to use IPC mechanisms and shared memory. I want to create a simple Publisher/Subscriber example or use an existing example by using the iceoryx2 crate.

I have imported the publish_subscribe example in my own workspace, and included iceoryx2 crate in .toml file.
It looks like this:

[package]
name = "iceoryx2"
description = "Iceoryx2 examples"
edition = "2021"
version = "0.1.0"

[dependencies]
iceoryx2 = { version = "0.2.2" }

Yet, when I try the run the publisher, it throws an error .send() not found in SampleMut. I would like to know what is it that I might be doing wrong or missing here, or is it an existing issue?

Command:
cargo run --bin publisher

Help would be appreciated. Thanks 👍

@antaradey-itk sample.send() is a new API only available on the main branch which eventually will become v0.3.

You can have a look at https://docs.rs/iceoryx2/0.2.2/iceoryx2/ for the v0.2 API. Spoiler alert ... you have to use publisher.send(sample) :)

Oh. That makes sense. Thank you for your help.
