Trait rquickjs::FromJs[−][src]

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

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.

Required methods

pub fn from_js(ctx: Ctx<'js>, value: Value<'js>) -> Result<Self, Error>[src]
