Crate rquickjs

High-level bindings to quickjs

The quickrjs crate provides safe high-level bindings to the quickjs javascript engine. This crate is heavily inspired by the rlua crate. # The Runtime and Context objects The main entry point of this library is the Runtime struct. It represents the interperter state and is used to create Context objects. As the quickjs library does not support threading the runtime is locked behind a mutex. Multiple threads cannot run as script or create objects from the same runtime at the same time. The Context object represents a global environment and a stack. Contexts of the same runtime can share javascript objects like in browser between frames of the same origin.

Converting Values

This library has multiple traits for converting to and from javascript. The ToJs, ToJsMulti traits are used for taking rust values and turning them into javascript values. ToJsMulti is specificly used for place where a specific number of values need to be converted to javascript like for example the arguments of functions. FromJs is for converting javascript value to rust. Note that this trait does some automatic coercion. For values which represent the name of variables or indecies the trait ToAtom is available to convert values to the represention quickjs requires.
