Enum RegistryEvent 

pub enum RegistryEvent {
    Register {
        type_name: &'static str,
    },
    RegisterCompleted {
        type_name: &'static str,
    },
    Get {
        type_name: &'static str,
        found: bool,
    },
    Contains {
        type_name: &'static str,
        found: bool,
    },
    Clear {},
}

Events emitted by the registry during operations.

These events are passed to the tracing callback set via set_trace_callback. The Clone derive allows callbacks to store or forward events if needed.

For register, two events are emitted per call: Register fires before the value is stored (so a panic during storage is visible in the log), and RegisterCompleted fires after the value is successfully stored. If only Register appears without a following RegisterCompleted, the store panicked.

Examples

use singleton_registry::RegistryEvent;

let event = RegistryEvent::Register { type_name: "i32" };
assert_eq!(event.to_string(), "register { type_name: i32 }");

Variants

Register

A register call was received. Fires before the value is stored. Followed by RegisterCompleted on success.

Fields

type_name: &'static str

The type name of the value being registered (e.g., “i32”, “alloc::string::String”)

RegisterCompleted

A value was successfully stored in the registry. Fires after the insert.

Fields

type_name: &'static str

The type name of the value that was stored

Get

A value was requested from the registry.

Fields

type_name: &'static str

The type name that was requested

found: bool

Whether the value was found in the registry

Contains

A type existence check was performed.

Fields

type_name: &'static str

The type name that was checked

found: bool

Whether the type exists in the registry

Clear

The registry was cleared.
