Trait ConfigKey 

pub trait ConfigKey: 'static {
    type Config: Send + Sync + 'static;

    const NAME: &'static str;
}

The key trait for identifying configuration in Kit.

Each configuration is identified by a unique key type that implements this trait. The Config associated type specifies the configuration value type. The NAME constant provides a diagnostic name for error messages.

Type Constraints

The Config type must satisfy Send + Sync + 'static for thread-safe storage. Note: Config must be Sized (no ?Sized bound) because ArcSwap<T> requires T: Sized.

The key type itself must satisfy 'static for TypeId stability.

Example

use trait_kit::core::config::ConfigKey;

struct MyConfig;
impl ConfigKey for MyConfig {
    type Config = i32;
    const NAME: &'static str = "my_config";
}

assert_eq!(MyConfig::NAME, "my_config");

Required Associated Constants

const NAME: &'static str

The diagnostic name for this config key. Used in error messages like MissingConfig { key: "logger_config" }.

Required Associated Types

type Config: Send + Sync + 'static

The configuration value type. Must satisfy Send + Sync + 'static and Sized.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
