Types

type Action added in v0.4.9 

type Action interface {
	// Execute executes this action, returning error if any.
	Execute(ctx context.Context) error
	// Rollback rollbacks this action, returning error if any.
	Rollback() error
}

Action is an abstraction of some action that can be rolled back.

type ActionQueue added in v0.4.9 

type ActionQueue struct {
	// contains filtered or unexported fields
