The command cargo test --release
is used in Rust programming language to run tests on the code in release mode. Let's break down the command:
-
cargo
: This is the command-line tool that ships with the Rust programming language. It is used for managing Rust projects, building, testing, and other related tasks. -
test
: This subcommand is used to run tests on the Rust code. It looks for test functions within the code and executes them. -
--release
: This is an optional flag that is used to build and run the tests in release mode. In release mode, the code is optimized for performance and may provide faster execution compared to the default debug mode. The release mode eliminates some debug assertions, inlining functions, and applying other optimizations that can lead to better performance.
So, when executing the cargo test --release
command, Rust will compile and run the code's tests in release mode, providing better performance optimization.
