Function quickjs_runtime::quickjs_utils::sets::size_q

pub fn size_q(
    q_ctx: &QuickJsRealmAdapter,
    set: &QuickJsValueAdapter,
) -> Result<i32, JsError>

get the number of entries in a Set

Example

use quickjs_runtime::builder::QuickJsRuntimeBuilder;
use quickjs_runtime::quickjsvalueadapter::QuickJsValueAdapter;
use quickjs_runtime::quickjs_utils::primitives;
use quickjs_runtime::quickjs_utils::sets::{add_q, new_set_q, size_q};

let rt = QuickJsRuntimeBuilder::new().build();
rt.exe_rt_task_in_event_loop(|q_js_rt| {
   let q_ctx = q_js_rt.get_main_realm();
   let my_set: QuickJsValueAdapter = new_set_q(q_ctx).ok().unwrap();
   let value = primitives::from_i32(23);
   add_q(q_ctx, &my_set, value).ok().unwrap();
   let i_size = size_q(q_ctx, &my_set).ok().unwrap();
   assert_eq!(i_size, 1);
});
