Обсуждение на тему: Java rust
Java rust
Я хочу сделать некоторые сравнения java и rust для начинающего rust программиста. Consider graalvm a recently released vm that gives zero-cost interoperability between various languages (including java and rust compiled into llvm-bitcode). Do you really need more explanation? Create the skeleton methods in java. At this point, the library contains the implementation, and the integration is done. Old-timers will have realized those are the same steps as when you need to integrate with c or c.
Экосистема java обширна и может решить практически любую проблему, с которой вы столкнетесь. Тем не менее, его возраст проявляется в нескольких частях, что делает его неуклюжим и непривлекательным для некоторых разработчиков java - разработчиков, которые могут быть заинтересованы в rust, одном из перспективных языков, которые конкурируют за внимание разработчиков. The java logging layer in questdb is custom, but weve managed to wire it up to the ubiquitous rust log crate to send all rust logging to java. Integrating logging is valuable it not only allows us to sprinkle info! And error! Logs throughout our code, but also gives us an insight into other dependencies we might be working with.
Jni is a set of criteria for java to interact with other languages, mainly the c language, and the official provides a c-based c interface. The theoretical language supporting c api can interact with the java language, and rust is one of them. Rust and java can call each other using the original jni interface, but the process is cumbersome the rust community already has a set of safe interfaces in place based on the original jni interface, the name of which is jni, which is easy to develop. What rust code is needed to invoke the java method and access the freshly-populated rgbs array? I intend to call topixels.
Rendertopixelsshape3 from a rust main() function, so the rust code will have to construct the jni environment. You have to use the invocation feature on the jni crate both rust and java are imperative languages with object-oriented features. So at its most basic the syntax of rust should feel familiar for a java developer. .
