rustup-init.sh:tldr:d3faf
This command runs the rustup-init
script with the argument --default-toolchain
followed by a value specified by the variable ${toolchain}
.
Here is a breakdown of what each part of the command means:
-
rustup-init.sh
:rustup-init.sh
is a script provided by Rustup, which is a command-line toolchain installer for Rust programming language. This script initializes the Rust environment and sets up the necessary tools and configurations. -
--default-toolchain
: This is an option provided byrustup-init.sh
that allows you to set the default toolchain for the Rust programming language. Toolchains in Rust represent different versions of the Rust compiler and associated tools. -
${toolchain}
: This is a placeholder or variable that should be replaced with the desired toolchain version. It allows you to specify the specific Rust toolchain version you want to set as the default. For example, if${toolchain}
is replaced withstable
, it will set the default toolchain to the stable version of Rust.
To use this command effectively, replace ${toolchain}
with the desired toolchain value, such as stable
, beta
, or nightly
. Example usage could be:
rustup-init.sh --default-toolchain stable
This will run the rustup-init
script and set the stable version of Rust as the default toolchain.
