Expand description

An owned TVMPODValue. Can be converted from a variety of primitive and object types. Can be downcasted using try_from if it contains the desired type.

Example

use std::convert::{TryFrom, TryInto};
use tvm_sys::RetValue;

let a = 42u32;
let b: u32 = tvm_sys::RetValue::from(a).try_into().unwrap();

let s = "hello, world!";
let t: RetValue = s.to_string().into();
assert_eq!(String::try_from(t).unwrap(), s);
