EventHandlerFunc is a wrapper type to allow a function to fulfull the EventHandler interface by calling the function.

Aggregate defines the necessary methods for acting interacting with an event sourced application. Aggregates receives requests for state changes in t

Application represents an event sourced application. Any interaction with an application happens by sending it commands. Commands are messages expre

BcryptedPassword is an implementation for securely handling password parameters. It uses the bcrypt algorithm for hashing passwords.

Clock is an interface for providing the current time. This interface exists to decouple objects that need access to the current time from the system

Command represents a message sent to your application with the intention to change application state. Commands are named in the imperative, e.g. "sig

CommandDefinition is used for defining the commands accepted by the application. Essentially it is a dynamically built definition of messages the sys

CommandHandler defines the interface for handling commands.

CommandResult represents the result of the application handling a command.

Email is an implementation of value for handling email addresses. It parses email addresses according to RFC 5322, e.g. "Barry Gibbs <bg@example.com>"

Event represents a state change that has occurred. Events are named in the past tense, e.g. "user.signed-up".

EventHandler defines the interface for processing events.

EventPublisher defines the interface for publishing events in aggregates.

EventStore defines the necessary operations for persisting events and restoring application state from the log of persisted events.

EventStoreTest encapsulates the tests for the EventStore interface. Any compliant implementation of an EventStore should pass these tests. This type

EventsInMemory is an in-memory implementation of an event store.

EventsOnDisk is a persistent, file-based implementation of an EventStore. Events are serialized as JSON and appended to a log file. Storing and repl

Form defines how to access form values. This allows commands to fill in parameters automatically. This interface is modelled after net/http.Request

Identifier is a value for handling parameters that serve as identifiers. It accepts any string consisting only of dashes, lowercase letters and digit

StaticClock implements the Clock interface by returning a static time. Its intended use is in test cases.

String is an implementation of Value for handling string parameters.

SystemTime wraps time.Now to implement the Clock interface.

Time is an implementation of Value for handling timestamps. It works with timestamps formatted according to time.RFC3339Nano.

ValidationError captures errors about the values of a command's parameter or the state of a whole aggregate. Return errors of this type by the method

Value is defines the interface for converting text into Go values. A value is used for capturing, sanitizing and validating the parameters accepted by

testAggregate is a dummy aggregate used for testing. This type is included in the main package, because it is referenced by EventStoreTest.
