The command "rustup show" is used in the Rust programming language's toolchain management system called "rustup". When executed, this command displays information about the currently installed versions of Rust toolchains on your system.
The output of "rustup show" typically includes the following information:
-
The active toolchain: It indicates the current default toolchain being used by Rust. This toolchain includes the specific version of the Rust compiler and associated tools.
-
Installed toolchains: It lists all the available Rust toolchains installed on your system. This can include both stable and beta versions, as well as nightly builds.
-
Installed components: It shows the additional components that are installed alongside the Rust toolchain. These components may include specific libraries, documentation, or optional tools.
-
Installed targets: Rust supports compiling code for different target platforms. This section displays the target platforms that are installed and available for use.
This command is helpful for checking the status of your Rust toolchain installation, confirming the active toolchain, and identifying additional components or targets that may be useful for your development needs.
