//! A mock implementation of `EventpOps` generated by [mockall].
//! See the [mockall] documentation for more information.
//!
//! # Examples
//!
//! ```rust
//! use mockall::predicate;
//! use eventp::{interest, EventpOps, mock::MockEventp};
//!
//! // Create a new mock object.
//! let mut mock = MockEventp::new();
//!
//! // Set an expectation for the `modify` method.
//! // It expects to be called exactly once with fd=5 and EPOLLIN.
//! // When called, it will return Ok(()).
//! mock.expect_modify()
//!     .with(predicate::eq(5), predicate::eq(interest().read()))
//!     .times(1)
//!     .returning(|_fd, _interest| Ok(()));
//!
//! // Call the method. This will be checked against the expectation.
//! let result = mock.modify(5, interest().read());
//!
//! // Assert that the call was successful.
//! assert!(result.is_ok());
//!
//! // When `mock` goes out of scope at the end of this block, mockall will
//! // verify that all expectations were met (e.g., that `modify` was called exactly once).
//! ```
