This is a naive implementation that can be extended if needed.

How it works:

1. IsNotEmptyArgument argument decorator "registers" validation in the target object (just an array of strings like <methodName>:<parameterIndex>:<validatorName>)
2. ValidateArguments method decorator reads all registered validations and executes them.

This scheme with 2 decorators instead of just one argument decorator is only needed because argument level decorator can't access actual argument value (it's weird)

Usage example:

export class MyClass {
    @ValidateArguments
    async myMethod(@IsNotEmptyArgument test: string): Promise<void> {
        ...
    }
}
