- # Enable static linking for C runtime library on Windows.
- #
- # Rust uses the msvc toolchain on Windows,
- # which by default dynamically links the C runtime (CRT) to the binary.
- #
- # This creates a runtime dependency on the Visual C++ Redistributable (`vcredist`),
- # meaning the target machine must have `vcredist` installed for the application to run.
- #
- # Since `portable` version doesn't have an installer,
- # we can't rely on it to install dependencies, so this config.
- #
- # Basically:
- # - The `+crt-static` flag instructs the Rust compiler to statically link the C runtime for Windows builds.\
- # - To avoids runtime errors related to missing `vcredist` installations.
- # - Results in a larger binary size because the runtime is bundled directly into the executable.
- #
- # For MSVC targets specifically, it will compile code with `/MT` or static linkage.
