| //! `libtock_runtime` provides the runtime for Tock process binaries written in |
| //! Rust as well as interfaces to Tock's system calls. |
| //! |
| //! `libtock_runtime` is designed for statically-compiled binaries, and needs to |
| //! know the location (in non-volatile memory and RAM) at which the process will |
| //! execute. It reads the `LIBTOCK_PLATFORM` variable to determine what location |
| //! to build for (see the `layouts/` directory to see what platforms are |
| //! available). It expects the following cargo config options to be set (e.g. in |
| //! `.cargo/config`): |
| //! ``` |
| //! [build] |
| //! rustflags = [ |
| //! "-C", "relocation-model=static", |
| //! "-C", "link-arg=-Tlayout.ld", |
| //! ] |
| //! ``` |
| //! If a process binary wants to support another platform, it can set the |
| //! `no_auto_layout` feature on `libtock_runtime` to disable this functionality |
| //! and provide its own layout file. |
