Hi Alex,

Thanks for reviewing the changes.

The Rust build now includes additional dependencies such as pkg-config, 
ninja, openssl
which are required for building rust and ensuring better compatibility 
across various build
environments.
(https://github.com/rust-lang/rust/blob/master/INSTALL.md#dependencies)

I believe the increased time is a result of theses added components as 
they can trigger
more comprehensive configuration and build steps, which naturally extend 
the overall
build time.
