wasm_split_macros
This crate provides macros that are used along with the wasm_split_helpers crate, which allows you to indicate that certain functions are appropriate split points for lazy-loaded code.
A build tool that supports this approach (like cargo-leptos) can then split a WebAssembly (WASM) binary into multiple chunks, which will be lazy-loaded when a split function is called.
This crate was adapted from an original prototype, which you can find here, with an in-depth description of the approach here.
This functionality is provided in Leptos by the #[lazy] and #[lazy_route] macros.
