Function quickjs_runtime::quickjs_utils::maps::size_q

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

get the number of entries in a map

Example

use quickjs_runtime::builder::QuickJsRuntimeBuilder;
use quickjs_runtime::quickjs_utils::maps::{new_map_q, set_q, size_q};
use quickjs_runtime::quickjsvalueadapter::QuickJsValueAdapter;
use quickjs_runtime::quickjs_utils::primitives;

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_map: QuickJsValueAdapter = new_map_q(q_ctx).ok().unwrap();
   let key = primitives::from_i32(12);
   let value = primitives::from_i32(23);
   set_q(q_ctx, &my_map, key.clone(), value).ok().unwrap();
   let i_size = size_q(q_ctx, &my_map).ok().unwrap();
   assert_eq!(i_size, 1);
});
