Crate disponent 

disponent

An alternative to dyn Trait for dispatching to multiple implementations.

Example

Use the declare! macro to define a trait and enum together. The enum will implement the trait by delegating method calls to its variants.

use disponent::declare;

declare!(
    pub enum FooOrBar {
        Foo(Foo),
        Bar(Bar),
    }

    pub trait SayHello {
        fn say_hello(&self);
    }
);

Configuration

Use #[disponent::configure(...)] on the enum with:

• inherent: Generate inherent methods (vs trait impl)
• inline: Add #[inline] to methods
• from: Generate From<T> for Enum impls
• try_into: Generate TryInto<T> for Enum impls

Remote Traits

Use #[disponent::remote(...)] on the trait to implement a trait defined elsewhere.

Macros

declare

Declare a trait and enum together, generating forwarding methods.

Attribute Macros

configure

Configure the enum forwarding behavior.

remote

Use a remote trait instead of the declared trait.
