authorization

type Authorization interface {
	// IsEnabled returns true if the authorization is enabled, false otherwise.

	// GetUser returns the user information from the context. The user information will depend on the implementation.
	// While implementing this method, consider that the user information is not guaranteed to be set in the context.
	// You should consider the case where the context can be empty and that the function can be called from an anonymous endpoint.
	// To check if it is called from an anonymous endpoint, you can use the function utils.IsAnonymous.
	// In case the context is not empty, and it is not an anonymous endpoint, the user information should be set in the context.
	// If it is not the case, you should return an error. All further functions are dependant on the results of theses decisions.
	GetUser(ctx echo.Context) (any, error)

	// Middleware returns the middleware function to be used in the echo server.
	// This middleware is responsible for finding the token in the request, validating it and extracting it in the context.
	// In case the token is not valid, it will prevent the request from being processed and return an error.
	// The middleware should be used before any other middleware that requires the user information to be set in the context.

	// GetUserProjects returns the list of the project the user has access to in the context of the role and the scope requested.
	// If the request scope is global, then it should return a single project with the wildcard value ("*") as it means that the user has access to a global resource and not a project resource.
	// The function can return also a single project with the wildcard value ("*") if the user has access to all the projects with the requested scope and action.
	// Be aware that this function cannot be called from an anonymous endpoint.
	// In case the user information is not found in the context, the implementation should return an error.
	// Be aware also this function is called after checking if the user has the permission to access to the resource with the requested scope and action, so it is not necessary to check the permission again in this function.

	// In case the user information is not found in the context, the implementation should return false.

	// RefreshPermissions refreshes the permissions.
	// We know this method is relative to the implementation and should not appear in the interface.
	// This is convenient to have it here when the implementation is keeping the permissions in memory.
	// And since it is a single method, it does not hurt to have it in the interface as it is straight forward to implement it if it's unnecessary.
	// Just return nil.
