For now I have been developing the application using Rust language for several days. In general, the experience is great. as well as have described their business logic using types system - The compiler guides my development and tells in which place is I making mistakes and how I can fix them - which is ok. The next thing that rust - is the language of C-family and it is compilable and have abstractions similar to Python with zero execution time cost - which let’s program to execute a bot faster than C++ apps do - which is also OK. most advanced memory management by default - which kills segmentation fault problems before they even have reason to appear. but while writing the ap. - i met the worst thing which slows me down. As long as QML is interpreted language - it can only be checked at runtime - otherwise i have white screen problem, after which i have to modify code again,compile i. pack an RPM and deploy it again. here’s why this problem is possible to solve at compile time: rust has libraries which let’s develop embedded HTML templates into backed code by itself,and the syntax uses native rust macros language system - which makes written and embedded HTML to be checked at compile time with great error description. rust even let’s the queries to be verified with consistency of database on compile time. so for improving speed of development, stability, and reacher app development cycle - I do request official rust SDK for Sailfish OS. for those who have developed at least few projects in rust after C++ and Python - will understand me definitely.
