Derive Macro Encapsulate

#[derive(Encapsulate)]
{
    // Attributes available to this derive:
    #[enumcapsulate]
}

Umbrella derive macro.

The following use of the Encapsulate umbrella derive macro:

use enumcapsulate::Encapsulate;

#[derive(Encapsulate)
enum Enum {
    // ...
}

is equivalent to the following:

// ...

#[derive(
    From,
    TryInto,
    FromVariant,
    IntoVariant,
    AsVariant,
    AsVariantMut,
    AsVariantRef,
    VariantDowncast,
)]
enum Enum {
    // ...
}

If you wish to opt out of a select few of Encapsulate’s trait derives, then you can do so by use of an #[enumcapsulate(exclude(…))] attribute on the enum itself, such as if you wanted to exclude From and TryInto:

#[derive(Encapsulate)]
#[enumcapsulate(exclude(From, TryInto))]
enum Enum {
    // ...
}
