pub struct EsValueFacade { /* fields omitted */ }

Implementations

impl EsValueFacade

pub fn stringify(&self) -> Result<String, EsError>

pub fn as_js_value(
    &mut self,
    q_ctx: &QuickJsContext
) -> Result<JSValueRef, EsError>

convert the value to a JSValueRef

pub fn from_jsval(
    q_ctx: &QuickJsContext,
    value_ref: &JSValueRef
) -> Result<Self, EsError>

convert a JSValueRef to an EsValueFacade

pub fn get_str(&self) -> &str

get the String value

pub fn get_i32(&self) -> i32

pub fn get_array(&self) -> Result<Vec<EsValueFacade>, EsError>

get the array value

pub fn get_object(&self) -> Result<HashMap<String, EsValueFacade>, EsError>

get the object value

pub fn is_string(&self) -> bool

check if the value is a String

pub fn is_i32(&self) -> bool

check if the value is a i32

pub fn is_f64(&self) -> bool

check if the value is a f64

pub fn is_boolean(&self) -> bool

check if the value is a bool

pub fn is_object(&self) -> bool

check if the value is an object

pub fn is_promise(&self) -> bool

check if the value is a Promise

pub fn is_array(&self) -> bool

check if the value is an array

pub fn is_function(&self) -> bool

check if the value is an function

pub fn is_null(&self) -> bool

check if the value is null

pub fn is_undefined(&self) -> bool

check if the value is undefined

pub fn invoke_function_sync(
    &self,
    arguments: Vec<EsValueFacade>
) -> Result<EsValueFacade, EsError>

invoke the Function represented by this EsValueFacade

pub async fn invoke_function(
    &self,
    arguments: Vec<EsValueFacade>
) -> Result<EsValueFacade, EsError>

invoke the Function represented by this EsValueFacade

pub fn invoke_function_batch_sync(
    &self,
    arguments: Vec<Vec<EsValueFacade>>
) -> Vec<Result<EsValueFacade, EsError>>

invoke a function multiple times with a different set of arguments

pub fn invoke_function_batch(
    &self,
    arguments: Vec<Vec<EsValueFacade>>
) -> Result<(), EsError>

invoke a function multiple times with a different set of arguments

pub fn get_promise_result_sync(&self) -> Result<EsValueFacade, EsValueFacade>

get the result of a Promise, this method blocks until the Promise is fulfilled. The Result will be an Ok if the Promise was resolved or an Err if the Promise was rejected

pub fn get_promise_result(
    &self
) -> impl Future<Output = Result<EsValueFacade, EsValueFacade>>

wait for the result of a Promise async. The Result will be an Ok if the Promise was resolved or an Err if the Promise was rejected

Example

use quickjs_runtime::esruntimebuilder::EsRuntimeBuilder;
use quickjs_runtime::esscript::EsScript;
use futures::executor::block_on;
use quickjs_runtime::esvalue::EsValueFacade;
pub async fn test_async(esvf: EsValueFacade) -> i32 {
   let prom_res = esvf.get_promise_result().await;
   let res_esvf = prom_res.ok().unwrap();
   return res_esvf.get_i32();
}

let rt = EsRuntimeBuilder::new().build();
let esvf = rt.eval_sync(EsScript::new("test_async_prom,es", "(new Promise((resolve, reject) => {setTimeout(() => {resolve(1360)}, 1000);}));")).ok().expect("script failed");
let i = block_on(test_async(esvf));
assert_eq!(i, 1360);

pub fn is_error(&self) -> bool

pub fn get_error(&self) -> EsError
