Macro tokio_test::assert_ok

macro_rules! assert_ok {
    ($e:expr) => { ... };
    ($e:expr,) => { ... };
    ($e:expr, $($arg:tt)+) => { ... };
}

Asserts that the expression evaluates to Ok and returns the value.

This will invoke the panic! macro if the provided expression does not evaluate to Ok at runtime.

Custom Messages

This macro has a second form, where a custom panic message can be provided with or without arguments for formatting.

Examples

use tokio_test::assert_ok;

let n: u32 = assert_ok!("123".parse());

let s = "123";
let n: u32 = assert_ok!(s.parse(), "testing parsing {:?} as a u32", s);
