Types ¶
type State ¶
type State interface { // Load reads the state from the storage into the memory. Load() error // Save writes the state from the memory into the storage. Save() error // Loaded returns true if the state is loaded into the memory. Loaded() bool // Changed returns true if the in-memory state has changed. Changed() bool // Get retrieves the state for the key into the state entry which must be // provided as pointer see example. // // For example: // // type T struct { // F int `yaml:"a,omitempty"` // B int // } // var t T // State.Get("my_key", &t) // Get(StateEntryKey, StateEntry) error // Set updates the state entry for the key. The state entry must not be // provided as pointer see example. // // For example: // // type T struct { // F int `yaml:"a,omitempty"` // B int // } // var t T // State.Set("my_key", t) // Set(StateEntryKey, StateEntry) error }
type StateEntry ¶
type StateEntry = interface{}
type StateEntryKey ¶
type StateEntryKey = string
type StateStorage ¶
type StateStorage interface { // Read loads the state from the storage. // // Must not return an error in case the state does not exist in the // storage but an empty RawState. Read() (RawState, error) // Write saves the state to the storage. Write(RawState) error // TagName returns the tag name used for additional field configuration. TagName() string }
