For many years, C has effectively been the “lingua franca” of the computing world. It’s pretty hard to combine code from two different programming languages in the same process–unless one of them is C. The same could theoretically be true for Rust, but in practice there are a number of obstacles that make that harder than it needs to be. Building out silky smooth language interop should be a core goal of helping Rust to target foundational applications.

Rust turns 10 this year. It’s a good time to take a look at where we are and where I think we need to be going. This post is the first in a series I’m calling “Rust in 2025”. This first post describes my general vision for how Rust fits into the computing landscape. The remaining posts will outline major focus areas that I think are needed to make this vision come to pass.
