Building for older os #10

Closed mercurial-moon closed 4 weeks ago

Hi,

I try to build railroad_dsl with an older toolchain (1.77) for making it work Windows 7. My build system has a newer OS however I want to run the built exe on older os like Windows 7.

While building I get error like

error[E0658]: use of unstable library feature 'lazy_cell' on render.rs line 67 67 | static USVG_OPTS: std::sync::LazyLock = std::sync::LazyLock::new(|| {

The crate doesn't have a MSRV, the most recent Rust-compiler is assumed to be available. Windows7 itself is EOL, so this is a tough ask anyway.

The most simple way forward would be to make the railroad/resvg-feature optional, which allows this crate to compile on previous compilers, yet losing the rendering-ability. Can you submit a PR for that?

Hi, not well versed in rust... In the end had to download an older rust environment, and got the app built using that.
