rustup:tldr:18080
This command is used to build a Rust project using a specific toolchain.
Here is a breakdown of the different parts:
-
rustup
: This is a command-line tool that is used to manage Rust installations. It allows you to install and switch between different versions of the Rust compiler. -
run
: This subcommand ofrustup
is used to run a command within a specific Rust toolchain. It ensures that the appropriate version of the Rust compiler and associated tools are used. -
${toolchain_name}
: This represents a placeholder for the name of the desired toolchain. It should be replaced with the actual name of the toolchain you want to use. Toolchains in Rust are different versions of the compiler and associated tools. Examples of toolchain names are "stable", "beta", or "nightly". You can install additional toolchains usingrustup toolchain install
. -
cargo
: This is the Rust package manager and build tool. It is used to manage dependencies and build Rust projects. -
build
: This is a subcommand ofcargo
used to build the Rust project located in the current directory. It gathers dependencies, compiles the code, and produces the executable or library according to the instructions in the project'sCargo.toml
file.
Putting it all together, the command rustup run ${toolchain_name} cargo build
ensures that the specified toolchain is used, and then runs cargo build
to build the Rust project in the current directory.
