quick-impl
is a Rust procedural macro that simplifies working with enums and structs by generating common methods and traits for each variant or field. This helps reduce boilerplate code and enhances the ergonomics of using enums and structs in your Rust projects.
as_ref
- Returns an immutable reference to the associated data of the enum variant.as_ref_mut
- Returns a mutable reference to the associated data of the enum variant.from
- Creates an instance of the enum variant from the associated data.into
- Converts the enum into the associated data of the variant, returning an Option
.is
- Checks if the enum variant matches a specified variant.set
- Replaces the current instance with a new instance of the specified variant.try_into
- Converts the enum into the associated data of the variant, returning a Result
.Default
- Implements the Default
trait on the enum.From
- Implements the From
trait on the enum.TryInto
- Implements the TryInto
trait on the enum.TryFrom
- Implements the TryFrom
trait on the associated data.get
- A getter for the field. Returns a reference to the field.get_clone
- A getter for the field. Returns a clone of the field.get_mut
- A mutable getter for a field.into
- Converts the struct into the field.from
- Creates an instance from the field. Sets the other fields to their default value.set
- A setter for the field.take
- Returns the field and replaces it with its default value.with
- Returns the struct with the field modified.AsRef
- Implements the AsRef
trait on the struct.AsMut
- Implements the AsMut
trait on the struct.Borrow
- Implements the Borrow
trait on the struct.BorrowMut
- Implements the BorrowMut
trait on the struct.Deref
- Implements the Deref
trait on the struct.DerefMut
- Implements the DerefMut
trait on the struct.Into
- Implements the Into
trait on the struct.From
- Implements the From
trait on the struct.Add quick-impl

In your Rust code:
use quick_impl::QuickImpl;
#[derive(QuickImpl)]
enum YourEnum {
#[quick_impl(pub const is)]
Variant1,
#[quick_impl(pub as_ref, pub(crate) as_ref_mut, impl From)]
Variant2(i32),
// ... add attributes to other variants as needed
}
fn main() {
let instance = YourEnum::Variant1;
// Use generated methods on enum instances
assert!(instance.is_variant1());
let variant2_instance = YourEnum::from(42);
assert_eq!(*variant2_instance.as_variant2().unwrap(), 42);
}
