Macro spirit_tokio::delegate_resource_traits

macro_rules! delegate_resource_traits {
    (delegate impl ExtraCfgCarrier to $inner: ident on $type: ident;) => { ... };
    (delegate impl ResourceConfig to $inner: ident on $type: ident;) => { ... };
    ($(delegate $($trait: ident),* to $inner: ident on $type: ident;)*) => { ... };
}

Delegates listed traits into a field.

If a trait is implemented for a field of a type, this allows for implementing it on the container too by delegating it to the field. This is limited to these traits:

• ExtraCfgCarrier
• ResourceConfig

Examples

#[macro_use]
extern crate spirit_tokio;

// This one is trivial ‒ the real one would actually add some functionality or fields.
#[derive(Debug, Eq, PartialEq)]
struct Wrapper<Inner> {
    inner: Inner,
}

delegate_resource_traits! {
    delegate ExtraCfgCarrier, ResourceConfig to inner on Wrapper;
}
