# 🦀 `typed-fields`
Do you like strongly-typed structs?
`typed-fields` is a collection of macros that generate types following the
[newtype] pattern. The following types are currently supported:
- `name!` - a string-based type
- `number!` - a number-based type
- `secret!` - a type for secrets (requires the `secret` feature)
- `ulid!` - a type for ULIDs (requires the `ulid` feature)
- `url!` - a type for URLs (requires the `url` feature)
- `uuid!` - a type for UUIDs (requires the `uuid` feature)
## Example
The following example showcases the `number!` macro, which generates a new type
that is backed by an `i64`.
```rust
use typed_fields::number;
// Define a new type that is backed by an `i64`
number!(UserId);
fn main() {
// Create a new `UserId` from an `i64`
let id = UserId::new(42);
// Common traits like `Display` are automatically implemented for the type
println!("User ID: {}", id);
}
```
