Derive Macro Any

#[derive(Any)]
{
    // Attributes available to this derive:
    #[rune]
}

Macro to mark a value as external, which will implement all the appropriate traits.

This is required to support the external type as a type argument in a registered function.

#[rune(item = <path>)]

Specify the item prefix which contains this time.

This is required in order to calculate the correct type hash, if this is omitted and the item is defined in a nested module the type hash won’t match the expected path hash.

use rune::Any;

#[derive(Any)]
#[rune(item = ::process)]
struct Process {
    /* .. */
}

fn install() -> Result<rune::Module, rune::ContextError> {
    let mut module = rune::Module::with_crate("process")?;
    module.ty::<Process>()?;
    Ok(module)
}

#[rune(name = <ident>)] attribute

The name of a type defaults to its identifiers, so struct Foo {} would be given the name Foo.

This can be overrided with the #[rune(name = <ident>)] attribute:

use rune::Any;

#[derive(Any)]
#[rune(name = Bar)]
struct Foo {
}

fn install() -> Result<rune::Module, rune::ContextError> {
    let mut module = rune::Module::new();
    module.ty::<Foo>()?;
    Ok(module)
}
