Macro droptest::assert_drop_stats

macro_rules! assert_drop_stats {
    ($registry : expr, { $($field : ident : $expected : expr), + }) => { ... };
    ($registry : expr, { $($field : ident : $expected : expr), + }
 $(, $message : tt) *) => { ... };
}

Asserts that the registry’s current stats match the provided pattern.

Like assert!, this macro has a second form, where a custom panic message can be provided.

Examples

use droptest::prelude::*;

let registry = DropRegistry::default();
let guard = registry.new_guard();
let id = guard.id();

assert_drop_stats!(registry, { created: 1 });
// or:
assert_drop_stats!(registry, { dropped: 0 });
// or:
assert_drop_stats!(registry, { created: 1, dropped: 0 });
// or:
assert_drop_stats!(registry, { created: 1, dropped: 0 }, "an optional message");
