this is a template to get started with no_std and no_main in an windows environment
this project aims for people who want to quickly get started with no_std on winodws to reduce the file size of their application this project has been entirely made with rusts core features and the winapi crate
this project also has an allocator which is possible through wee_alloc. even tho its designed for wasm, it also works with #![no_std].
an allocater is required for some basic functionality of rust e.g. a vec![];
have rust installed for your system.
well first of all, it is recommended to use the nightly compiler because of some unstable features, and because its common practice to use nightly for #![no_std] aka in embedded environments (which we dont do)
you dont have to do it, but it would be better
i tried it with both stable and nightly, and both worked for me.
anyways, if you want to make sure that it works for you, you can install nightly with the following commands.
rustup toolchain install nightly
rustup default nightly
to switch back to stable use
rustup default stable
after you are ready:
run the project on a WINDOWS MACHINE with cargo run
in the root of the project is a hello_world_std.rs file
you can build it with rustc to an executable by running
rustc hello_world_std.rs
SPOILER ABOUT THE DIFFERENCE BELOW HERE

with hello_world_std.rs compiled to a binary the file size of the executable with stdlib was around 144kb
with my no_std lib version the file size is around 89kb with the template code unmodified.
