An interesting start to a language for sure. While the compiler is a bit pedantic, it is largely an OK developer experience. I found that the trick to using this language is whenever you want to do crimes with memory, just wrap it in unsafe. For ergonomics, I found that writing unsafe everywhere to be a little less comfortable.
Luckily this language seems to have a pretty good macro system, I found that I could write a macro that will do the function wrapping for me:
Code:
macro_rules! wrap_unsafe {
($($func:ident ( $($param:ident : $param_type:ty),* ) $(-> $return_type:ty)? $body:block)*) => {
$(
fn $func($($param : $param_type),*) $(-> $return_type)? {
unsafe { $body }
}
)*
};
}This way, memory crimes are just more ergonomic and comfortable.
Code:
wrap_unsafe! {
unsafe_example(buffer: &mut [u8; 2]) -> u32 {
let buffer_ptr = buffer.as_mut_ptr();
// Offset is unsafe
*buffer_ptr.offset(0) = 0xAA;
ptr_magic_value(buffer_ptr.offset(1));
buffer[0] as u32 + buffer[1] as u32
}
ptr_magic_value(ptr: *mut u8) {
// Deref of raw pointer
*ptr = 42;
}
}
fn main() {
let mut buffer: [u8; 2] = [0, 0];
println!("{}", unsafe_example(&mut buffer));
}
