enum_for_matches
enum_for_matches
runs a match arm for each enum variant passed into it
regardless of type. So, you can make a string out of an enum which wraps
numeric types individually, such as serde_value::Value
for example. See
README.md on GitHub for more information.
For example, this:
```rust enum TestEnum { I64(i64), U64(u64) }
let e = TestEnum::I64(80); let mut s = String::new();
enumformatches::run!(e, {TestEnum::I64(i) | TestEnum::U64(i)}, {s = i.to_string();}); eprintln!("{}", &s); ```
Would expand to:
rust
match e
{
TestEnum::I64(i) => { s = i.to_string(); }
TestEnum :: U64(i) => { s = i.to_string(); }
_ => { }
}
And print 80
.
This crate is considered feature complete. It uses a copious amount of
.clone()
's, many of which are probably removable. However, since this only
runs at compile time, on probably quite small vectors, I couldn't be bothered.
