Section III - Creating an Executable
Although this package was created as a library, we can make it dual binary and library by doing the following:
Modify the
Cargo.toml
file to point to a binary during build time
[[bin]]
name = "hello_world"
path = "src/bin/hello-world.rs"
Create a new bin folder in the src directory
Create a new file
hello-world.rs
in the bin directory with the following code
pub fn main() {
println!("Hello World");
}
Build and run the package
ArchConfWorkshopUser:~/environment/rust-daas (master) $ cargo run
Compiling rust-daas v0.1.0 (/home/ec2-user/environment/rust-daas)
Finished dev [unoptimized + debuginfo] target(s) in 0.35s
Running `target/debug/hello_world`
Hello World
There should now be an executable named hello_world in the /target/debug directory which you can execute directly.
ArchConfWorkshopUser:~/environment/rust-daas (master) $ cd ./target/debug/
ArchConfWorkshopUser:~/environment/rust-daas/target/debug (master) $ ./hello_world
Hello World
