1//! Storage operation events for simulation.
2//!
3//! These events are scheduled by SimStorageFile/SimStorageProvider and
4//! processed by SimWorld to simulate storage I/O with deterministic
5//! timing and fault injection.

7/// Storage operations that can be scheduled in the simulation.
8///
9/// Unlike network operations which model data delivery, storage operations
10/// model the completion of I/O requests. Each operation represents a
11/// pending I/O that completes at the scheduled time.
