Function javascriptcore_sys::JSValueProtect [] [src]

pub unsafe extern "C" fn JSValueProtect(ctx: JSContextRef, value: JSValueRef)

Protects a JavaScript value from garbage collection.

Use this method when you want to store a JSValue in a global or on the heap, where the garbage collector will not be able to discover your reference to it.

A value may be protected multiple times and must be unprotected an equal number of times before becoming eligible for garbage collection.
