type Cache struct {
	// contains filtered or unexported fields
}

Cache maps execution ids to states. When full, an arbitrary entry is evicted: a miss only costs a reload.

func New(size int) *Cache

New returns a cache bounded to size entries.

func (c *Cache) Drop(execID string)

Drop removes execID.

func (c *Cache) Get(execID string) (Entry, bool)

Get returns the cached entry of execID.

func (c *Cache) Put(execID string, e Entry)

Put stores an entry.

type Entry struct {
	State *fold.State
	Def   *flow.Flow
}

Entry is one cached state with its definition.
