Struct RegistrationFunc 

#[non_exhaustive]
pub struct RegistrationFunc(/* private fields */);

All auto-registration functions need to use this type for registration.

This is, usually, used by the derive macro, and not manually.

Implementations

impl RegistrationFunc

pub const fn new(register: fn(&Registry)) -> Self

Create a new RegistrationFunc from a register function.

The register function gets passed a Registry, which it must use to register one or more types.

The function must not have any side-effects. It may be called concurrently, in parallel, and from any thread (not only the main thread).

Example

#[derive(Debug)]
struct StringTemplate {
    template: &'static str,
}

// Usually, this `impl` is generated by the `Inject` proc-macro.
impl StringTemplate {
    pub(crate) fn register(registry: &Registry) {
        registry
            .register_transient::<StringTemplate, _>(|| StringTemplate { template: "" });
    }
}

// The construction must be `const`.
autoregister!(RegistrationFunc::new(
    StringTemplate::register
));
