Types

type CombinedSecretsResponse

type CombinedSecretsResponse struct {
	SecretsResponseBase
	NodeResponses []*api.Message `json:"node_responses"`
}

Gateway -> User response, which combines responses from several nodes

type FunctionsHandlerConfig

type FunctionsHandlerConfig struct {
	OnchainAllowlistChainID string `json:"onchainAllowlistChainId"`
	// Not specifying OnchainAllowlist config disables allowlist checks
	OnchainAllowlist *OnchainAllowlistConfig `json:"onchainAllowlist"`
	// Not specifying RateLimiter config disables rate limiting
	UserRateLimiter      *hc.RateLimiterConfig `json:"userRateLimiter"`
	NodeRateLimiter      *hc.RateLimiterConfig `json:"nodeRateLimiter"`
	MaxPendingRequests   uint32                `json:"maxPendingRequests"`
	RequestTimeoutMillis int64                 `json:"requestTimeoutMillis"`
}

type OnchainAllowlist

type OnchainAllowlist interface {
	job.ServiceCtx

	Allow(common.Address) bool
	UpdateFromContract(ctx context.Context) error
}

OnchainAllowlist maintains an allowlist of addresses fetched from the blockchain (EVM-only). Use UpdateFromContract() for a one-time update or set OnchainAllowlistConfig.UpdateFrequencySec for repeated updates. All methods are thread-safe.

func NewOnchainAllowlist

func NewOnchainAllowlist(client evmclient.Client, config OnchainAllowlistConfig, lggr logger.Logger) (OnchainAllowlist, error)

type OnchainAllowlistConfig

type OnchainAllowlistConfig struct {
	// ContractAddress is required
	ContractAddress    common.Address `json:"contractAddress"`
	ContractVersion    uint32         `json:"contractVersion"`
	BlockConfirmations uint           `json:"blockConfirmations"`
	// UpdateFrequencySec can be zero to disable periodic updates
	UpdateFrequencySec uint `json:"updateFrequencySec"`
	UpdateTimeoutSec   uint `json:"updateTimeoutSec"`
}

type PendingSecretsRequest

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

type SecretsListResponse

type SecretsListResponse struct {
	SecretsResponseBase
	Rows []SecretsListRow `json:"rows,omitempty"`
}

type SecretsListRow

type SecretsListRow struct {
	SlotID     uint   `json:"slot_id"`
	Version    uint64 `json:"version"`
	Expiration int64  `json:"expiration"`
}

type SecretsResponseBase

type SecretsResponseBase struct {
	Success      bool   `json:"success"`
	ErrorMessage string `json:"error_message,omitempty"`
}

type SecretsSetRequest

type SecretsSetRequest struct {
	SlotID     uint   `json:"slot_id"`
	Version    uint64 `json:"version"`
	Expiration int64  `json:"expiration"`
	Payload    []byte `json:"payload"`
	Signature  []byte `json:"signature"`
}

type SecretsSetResponse

type SecretsSetResponse struct {
	SecretsResponseBase
}
