Rust – Early Adopter

Rust is being widely adopted at this point among San Francisco Bay Area companies,. The adoption is low in other areas. Rust has moved from innovator to early adopter quadrants. This is due to its uptake within the infrastructure and networking data plane space. Habitat and Linkerd 2.0 have adopted Rust as their core platform. It is emerging as a natural partner for WebAssembly. This is helping to drive awareness. It is also important that Facebook has chosen to implement its Libra cryptocurrency using Rust.

“Rust definitely seems to have seen growth in the last year, and I’d move it from innovator to early adopter. They’ve been good at positioning it as a partner with Wasm, which is helping, I think.” – Charles Humble, Editor in Chief at InfoQ:
