Function step 

pub fn step<F, R>(name: impl Into<String>, body: F) -> R
where
    F: FnOnce() -> R,

Executes a step with the given name and body.

Steps are the building blocks of test reports. They provide a hierarchical view of what the test is doing and can be nested.

Example

use allure_core::runtime::{with_test_context, step};

with_test_context(|| {
    step("Login to application", || {
        step("Enter credentials", || {
            // Enter username and password
        });
        step("Click submit", || {
            // Click the submit button
        });
    });
});

Steps can also return values:

use allure_core::runtime::{with_test_context, step};

with_test_context(|| {
    let result = step("Calculate result", || {
        2 + 2
    });
    assert_eq!(result, 4);
});
