Types ¶
type Fetcher ¶
type Fetcher interface { State(ctx context.Context, stateId []byte) (state.BeaconState, error) StateRoot(ctx context.Context, stateId []byte) ([]byte, error) StateBySlot(ctx context.Context, slot primitives.Slot) (state.BeaconState, error) }
Fetcher is responsible for retrieving info related with the beacon chain.
type StateIdParseError ¶
type StateIdParseError struct {
// contains filtered or unexported fields
}
StateIdParseError represents an error scenario where a state ID could not be parsed.
func NewStateIdParseError ¶
func NewStateIdParseError(reason error) StateIdParseError
NewStateIdParseError creates a new error instance.
func (*StateIdParseError) Error ¶
func (e *StateIdParseError) Error() string
Error returns the underlying error message.
type StateNotFoundError ¶
type StateNotFoundError struct {
// contains filtered or unexported fields
}
StateNotFoundError represents an error scenario where a state could not be found.
func NewStateNotFoundError ¶
func NewStateNotFoundError(stateRootsSize int) StateNotFoundError
NewStateNotFoundError creates a new error instance.
func NewStateRootNotFoundError ¶
func NewStateRootNotFoundError(stateRootsSize int) StateNotFoundError
NewStateRootNotFoundError creates a new error instance.
func (*StateNotFoundError) Error ¶
func (e *StateNotFoundError) Error() string
Error returns the underlying error message.
type StateProvider ¶
type StateProvider struct { BeaconDB db.ReadOnlyDatabase ChainInfoFetcher blockchain.ChainInfoFetcher GenesisTimeFetcher blockchain.TimeFetcher StateGenService stategen.StateManager ReplayerBuilder stategen.ReplayerBuilder }
StateProvider is a real implementation of Fetcher.
func (*StateProvider) State ¶
func (p *StateProvider) State(ctx context.Context, stateId []byte) (state.BeaconState, error)
State returns the BeaconState for a given identifier. The identifier can be one of:
- "head" (canonical head in node's view)
- "genesis"
- "finalized"
- "justified"
- <slot>
- <hex encoded state root with '0x' prefix>
func (*StateProvider) StateBySlot ¶
func (p *StateProvider) StateBySlot(ctx context.Context, target primitives.Slot) (state.BeaconState, error)
StateBySlot returns the post-state for the requested slot. To generate the state, it uses the most recent canonical state prior to the target slot, and all canonical blocks between the found state's slot and the target slot. process_blocks is applied for all canonical blocks, and process_slots is called for any skipped slots, or slots following the most recent canonical block up to and including the target slot.
type StateRootNotFoundError ¶
type StateRootNotFoundError struct {
// contains filtered or unexported fields
}
StateRootNotFoundError represents an error scenario where a state root could not be found.
func (*StateRootNotFoundError) Error ¶
func (e *StateRootNotFoundError) Error() string
Error returns the underlying error message.
