rustc: Compile with high optimization.
$ rustc -O ${filename-rs}
try on your machine
The command "rustc -O ${filename-rs}" is used to compile a Rust source code file with optimization enabled.
Here's a breakdown of the command:
rustc: This is the Rust compiler command that is used to compile Rust source code files into executables.-O: This flag enables optimization during the compilation process. Optimization improves the performance and efficiency of the generated code.${filename-rs}: This is a placeholder that represents the name of the Rust source code file to be compiled. The actual file name should replace this placeholder when running the command.
Overall, the command instructs the Rust compiler (rustc) to compile the specified Rust source code file with optimization enabled.
