Safe unwrap replacements that log instead of panic.

.unwrap() and .expect() are useful during development but cause production outages when invariants break. This crate provides drop-in macro replacements that degrade gracefully: return a default value and emit a structured log instead of panicking.

Quick Reference

Before	After	For
`opt.unwrap()`	`unwrap_or_warn!(opt, default, "ctx")`	`Option<T>`
`res.unwrap()`	`result_or_warn!(res, default, "ctx")`	`Result<T, E>`
`s.parse::<T>().unwrap()`	`parse_or_warn!(s, T, default, "ctx")`	String parsing
`opt.expect("msg")`	`expect_or_error!(opt, default, "msg")`	Option soft-expect
`res.expect("msg")`	`expect_result_or_error!(res, default, "msg")`	Result soft-expect

All macros include file!() and line!() in the log output.

Example

use unwrap_safe::{unwrap_or_warn, result_or_warn, parse_or_warn};

// Option: return default on None
let name: Option<String> = None;
let display = unwrap_or_warn!(name, String::from("anonymous"), "user display name");
assert_eq!(display, "anonymous");

// Result: return default on Err
let val: Result<i32, String> = Err("timeout".into());
let count = result_or_warn!(val, 0, "request count");
assert_eq!(count, 0);

// Parse: return default on bad input
let port = parse_or_warn!("not_a_port", u16, 8080, "PORT env var");
assert_eq!(port, 8080);
