Overview ¶
Package state collects functionality for verifying states of network map members.
NetMapCandidateValidator type provides an interface for checking the network map candidates.

Types ¶
type NetMapCandidateValidator ¶
type NetMapCandidateValidator struct {
// contains filtered or unexported fields
}
NetMapCandidateValidator represents tool which checks state of nodes which are going to register in the NeoFS network (enter the network map).
NetMapCandidateValidator can be instantiated using built-in var declaration and currently doesn't require any additional initialization.
NetMapCandidateValidator implements github.com/nspcc-dev/neofs-node/pkg/innerring/processors/netmap.NodeValidator.
func (*NetMapCandidateValidator) SetNetworkSettings ¶
func (x *NetMapCandidateValidator) SetNetworkSettings(netSettings NetworkSettings)
SetNetworkSettings specifies provider of the NetworkSettings interface. MUST be called before any VerifyAndUpdate call. Parameter MUST NOT be nil.
func (*NetMapCandidateValidator) Verify ¶ added in v0.39.0
func (x *NetMapCandidateValidator) Verify(node netmap.NodeInfo) error
Verify checks state of the network map candidate described by netmap.NodeInfo parameter. Returns no error if status is correct, otherwise returns an error describing a violation of the rules:
status MUST be either ONLINE or MAINTENANCE; if status is MAINTENANCE, then it SHOULD be allowed by the network.
Verify does not mutate the parameter in a binary format. MUST NOT be called before SetNetworkSettings.
See also netmap.NodeInfo.IsOnline/SetOnline and other similar methods.
type NetworkSettings ¶
type NetworkSettings interface { // MaintenanceModeAllowed checks if maintenance state of the storage nodes // is allowed to be set, and returns: // no error if allowed; // ErrMaintenanceModeDisallowed if disallowed; // other error if there are any problems with the check. MaintenanceModeAllowed() error }
NetworkSettings encapsulates current settings of the NeoFS network and provides interface used for processing the network map candidates.
