You can specify multiple binaries using [[bin]], as mentioned here: [[bin]] name = “daemon” path = “src/daemon/bin/main.rs” [[bin]] name = “client” path = “src/client/bin/main.rs” Tip: If you instead put these files in src/bin/daemon.rs and src/bin/client.rs, you’ll get two executables named daemon and client as Cargo compiles all files in src/bin into executables with the same … Read more
Cargo passes some metadata to the compiler through environment variables, a list of which can be found in the Cargo documentation pages. The compiler environment is populated by fill_env in Cargo’s code. This code has become more complex since earlier versions, and the entire list of variables is no longer obvious from it because it … Read more
Rust uses static linking to compile its programs, meaning that all libraries required by even the simplest Hello world! program will be compiled into your executable. This also includes the Rust runtime. To force Rust to dynamically link programs, use the command-line arguments -C prefer-dynamic; this will result in a much smaller file size but … Read more
