rustc: Display architecture-specific optimizations for the current CPU.
$ rustc -C target-cpu=native --print cfg
try on your machine
This command runs the Rust compiler (rustc
) with specific options to determine the target CPU architecture and print the configuration (cfg
) options.
Here's a breakdown of the command:
rustc
: This is the command to run the Rust compiler.-C target-cpu=native
: The-C
flag tells the compiler to set a specific configuration option.target-cpu
is a configuration option that sets the target CPU architecture.native
indicates that the compiler should use the native CPU architecture of the machine running the command.--print cfg
: This option instructs the compiler to print the configuration options. Thecfg
command prints the configuration settings that affect the compilation process.
In summary, the command compiles the Rust code while specifying the target CPU architecture accordingly, and then prints out the configuration options being used for the compilation process.

never run a command you are not sure if it is safe.
