type IssuanceChainCache

type IssuanceChainCache interface {
	// Get returns the issuance chain associated with the provided hash.
	Get(ctx context.Context, key []byte) ([]byte, error)

	// Set inserts the key-value pair of issuance chain.
	Set(ctx context.Context, key []byte, chain []byte) error
}

IssuanceChainCache is an interface which allows CTFE binaries to use different cache implementations for issuance chains.

func NewIssuanceChainCache

func NewIssuanceChainCache(_ context.Context, cacheType Type, option Option) (IssuanceChainCache, error)

NewIssuanceChainCache returns noop.IssuanceChainCache for noop type or lru.IssuanceChainCache for lru cache type.

type Option

	Size int
	TTL  time.Duration
}

Option represents the cache option, which includes the cache size and time-to-live.
