# wireshift-fallback - Technical Spec
## Overview
Fallback worker backend for `wireshift`. This backend preserves the same typed request and completion contracts as the native `io_uring` path while executing unsupported or unavailable operations on a blocking worker pool.
## Architecture
The crate is organized into the following public modules:
- `net_ops`
- `ops`
- `pool`
## Guarantees
- `#![forbid(unsafe_code)]` where applicable; see `src/lib.rs` for the exact lint preamble.
- All public types have doc comments.
- Error messages are actionable where applicable.
## Public API Summary
Key entry points are exported from `src/lib.rs` via `pub mod` and `pub use` re-exports.
Consult the module-level documentation in each source file for function signatures and usage examples.
## Error Handling
- Standard `Result` / error types.
