Trait JsFn 

pub trait JsFn<A>:
    Send
    + Sync
    + 'static { }

Available on crate features js and std only.

A host function with typed, extractor-style arguments.

Implemented for closures of up to twelve JsArg arguments as well as for variadic closures taking a single JsArgs, returning any JsFnOutput. Extra call arguments are ignored (js style), missing ones error unless the parameter is an Option.

The A parameter is an inference marker; ignore it.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
