//! See <https://github.com/matklad/cargo-xtask/>.

|
|
//! This binary defines various auxiliary build commands, which are not
|
|
//! expressible with just `cargo`. Notably, it provides tests via `cargo test -p xtask`
|
|
//! for code generation and `cargo xtask install` for installation of
|
|
//! rust-analyzer server and client.
|
|
//!
|
|
//! This binary is integrated into the `cargo` command line by using an alias in
|
|
//! `.cargo/config`.
