How do I validate that engineers truly want a software?

Some 4 months back, I started work on a side project - Ngyn (pronounced \en · jn\\) which is a rust backend framework for rustaceans who would prefer use of macros and structs to build backend services.

So far, the project has reached some calmness with much of its features implemented already while others are in the works. But how do I verify that engineers would actually want to make use of it?

Ngyn took inspiration from nestjs and goes the platform-agnostic route. This means you can use any existing backend library or framework with ngyn.
