🦀 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)
• 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.

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);
}
