Macro cargo_emit::rustc_link_arg_bins

macro_rules! rustc_link_arg_bins {
    (to : $stream : expr, $($flag : expr), + $(,) ?) => { ... };
    ($($flag : expr), + $(,) ?) => { ... };
}

Tells Cargo to pass the -C link-arg=$flag option to the compiler, but only when building a binary target. Its usage is highly platform specific. It is useful to set a linker script or other linker options.

This is equivalent to:

println!("cargo:rustc-link-arg-bins=$flag");

Examples

let flag1 = // ...
let flag2 = // ...
cargo_emit::rustc_link_arg_bins!(
    flag1, flag2
);

or, in case you want it to emit to a custom stream:

let flag1 = // ...
let flag2 = // ...
let mut stdout = std::io::stdout();
cargo_emit::rustc_link_arg_bins!(
    to: stdout,
    flag1, flag2
);
