Trait rquickjs_core::FromJs[−][src]

pub trait FromJs<'js>: Sized {
    fn from_js(ctx: Ctx<'js>, value: Value<'js>) -> Result<Self>;
}

For converting javascript values to rust values

This trait automatically converts any value which can be represented as an object, like Array to one if it is required.
