Struct SuiteGuard

Source

pub struct SuiteGuard<T>where
    T: SuiteResource,
{ /* private fields */ }

Expand description

Guard for suite-wide shared resource

Uses OnceLock + Weak<Arc<T>> pattern to ensure:

Resource is initialized only once
Resource is dropped when last test completes

§Examples

use reinhardt_testkit::resource::{SuiteResource, SuiteGuard, acquire_suite};
use rstest::*;
use std::sync::{OnceLock, Mutex, Weak};

struct MySuite;

impl SuiteResource for MySuite {
    fn init() -> Self { Self }
}

static SUITE: OnceLock<Mutex<Weak<MySuite>>> = OnceLock::new();

#[fixture]
fn suite() -> SuiteGuard<MySuite> {
    acquire_suite(&SUITE)
}
