}

A record of a single oracle response.

Variants

Service(Vec<u8>)

The response from a service query.

Http(Response)

The response from an HTTP request.

Blob(BlobId)

A successful read or write of a blob.

Assert

An assertion oracle that passed.

Round(Option<u32>)

The block’s validation round.

Event(EventId, Vec<u8>)

An event was read.

EventExists(EventId)

An event exists.

Checkpoint

A checkpoint of the chain’s execution state was published. The execution-state dump is chunked into one or more BlobType::CheckpointExecutionState blobs whose content hashes are listed here in restore order; a bootstrapping node concatenates the bytes and feeds them to ExecutionStateView::restore_from_content.

Fields

execution_state_blobs: Vec<CryptoHash>

Content hashes of the execution-state-dump blobs, in restore order.

used_blobs: Vec<BlobId>

All blobs the chain references in its used_blobs set at the time of the checkpoint. A bootstrapping node must have each of these in shared blob storage before applying the checkpoint, otherwise subsequent operations on the chain could try to read blob content the node doesn’t actually have.

outbox_block_hashes: Vec<CryptoHash>

Hashes of every block on this chain that the chain’s outboxes still reference at the time of the checkpoint — i.e. the heights with cross-chain messages that recipients haven’t acknowledged yet. The current-epoch certificate over the checkpoint block transitively certifies these older blocks: a node that later receives one of these block’s bytes can verify the bytes hash to a hash in this set, without trusting the (possibly revoked) validator signatures on the older block’s own certificate.

inbox_cursors: Vec<(ChainId, Cursor)>

For each chain whose messages we’ve consumed, the next_cursor_to_remove of the corresponding inbox. A bootstrapping node uses these to seed each inbox’s restored_cursor, so subsequent sender re-pushes below that cursor are silently dropped (their effects are already baked into the restored execution state).

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for OracleResponse

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl InputType for OracleResponse

type RawValueType = OracleResponse

The raw type used for validator.

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

fn parse(value: Option<Value>) -> InputValueResult<Self>

Parse from Value. None represents undefined.

fn to_value(&self) -> Value

Convert to a Value for introspection.

fn as_raw_value(&self) -> Option<&Self::RawValueType>

Returns a reference to the raw value.

fn qualified_type_name() -> String

Qualified typename.

impl OutputType for OracleResponse

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

async fn resolve( &self, _: &ContextSelectionSet<'_>, _field: &Positioned<Field>, ) -> ServerResult<Value>

Resolve an output value to async_graphql::Value.

fn qualified_type_name() -> String

Qualified typename.

fn introspection_type_name(&self) -> Cow<'static, str>

impl PartialEq for OracleResponse

fn eq(&self, other: &OracleResponse) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
