Implementations
impl JsFunction
[src]
See Working with JavaScript Functions.
Example:
use napi::{JsFunction, CallContext, JsNull, Result}; #[js_function(1)] pub fn call_function(ctx: CallContext) -> Result<JsNull> { let js_func = ctx.get::<JsFunction>(0)?; let js_string = ctx.env.create_string("hello".as_ref())?.into_unknown()?; js_func.call(None, &[js_string])?; Ok(ctx.env.get_null()?) }
pub fn call(
&self,
this: Option<&JsObject>,
args: &[JsUnknown]
) -> Result<JsUnknown>
[src]
&self,
this: Option<&JsObject>,
args: &[JsUnknown]
) -> Result<JsUnknown>
pub fn new<V>(&self, args: &[V]) -> Result<JsObject> where
V: NapiValue,
[src]
V: NapiValue,

This method is used to instantiate a new JavaScript
value using a given JsFunction
that represents the constructor for the object.
