Struct BoxStatefulTester 

pub struct BoxStatefulTester { /* private fields */ }

A single-ownership stateful tester backed by Box<dyn FnMut() -> bool>.

BoxStatefulTester is the owned wrapper for zero-argument tests that need native FnMut() -> bool semantics. Calling StatefulTester::test may mutate state captured by the wrapped closure.

Implementations

impl BoxStatefulTester

pub fn new<F>(f: F) -> Self

where F: FnMut() -> bool + 'static,

Creates a new boxed stateful tester.

pub fn and<T>(self, next: T) -> BoxStatefulTester

where T: StatefulTester + 'static,

Combines this tester with another stateful tester using logical AND.

The second tester is evaluated only when the first tester returns true.

pub fn or<T>(self, next: T) -> BoxStatefulTester

where T: StatefulTester + 'static,

Combines this tester with another stateful tester using logical OR.

The second tester is evaluated only when the first tester returns false.

pub fn nand<T>(self, next: T) -> BoxStatefulTester

where T: StatefulTester + 'static,

Combines this tester with another stateful tester using logical NAND.

pub fn xor<T>(self, next: T) -> BoxStatefulTester

where T: StatefulTester + 'static,

Combines this tester with another stateful tester using logical XOR.

pub fn nor<T>(self, next: T) -> BoxStatefulTester

where T: StatefulTester + 'static,

Combines this tester with another stateful tester using logical NOR.

impl Not for BoxStatefulTester

type Output = BoxStatefulTester

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

fn into_box(self) -> BoxStatefulTester
