Struct linera_chain::block::Block

pub struct Block {
    pub header: BlockHeader,
    pub body: BlockBody,
}

Block defines the atomic unit of growth of the Linera chain.

As part of the block body, contains all the incoming messages and operations to execute which define a state transition of the chain. Resulting messages produced by the operations are also included in the block body, together with oracle responses and events.

Fields

header: BlockHeader

Header of the block containing metadata of the block.

body: BlockBody

Body of the block containing all of the data.

Implementations

impl Block

pub async fn header(&self, ctx: &Context<'_>) -> Result<&BlockHeader>

pub async fn body(&self, ctx: &Context<'_>) -> Result<&BlockBody>

impl Block

pub fn new(block: ProposedBlock, outcome: BlockExecutionOutcome) -> Self

pub fn message_bundles_for<'a>( &'a self, medium: &'a Medium, recipient: ChainId, certificate_hash: CryptoHash, ) -> impl Iterator<Item = (Epoch, MessageBundle)> + 'a

Returns the bundles of messages sent via the given medium to the specified recipient. Messages originating from different transactions of the original block are kept in separate bundles. If the medium is a channel, does not verify that the recipient is actually subscribed to that channel.

pub fn message_id_for_operation( &self, operation_index: usize, message_index: u32, ) -> Option<MessageId>

Returns the message_indexth outgoing message created by the operation_indexth operation, or None if there is no such operation or message.

pub fn message_id(&self, index: u32) -> MessageId

Returns the message ID belonging to the indexth outgoing message in this block.

pub fn message_by_id(&self, message_id: &MessageId) -> Option<&OutgoingMessage>

Returns the outgoing message with the specified id, or None if there is no such message.

pub fn required_blob_ids(&self) -> BTreeSet<BlobId>

Returns all the blob IDs required by this block. Either as oracle responses or as published blobs.

pub fn requires_blob(&self, blob_id: &BlobId) -> bool

Returns whether this block requires the blob with the specified ID.

pub fn oracle_blob_ids(&self) -> BTreeSet<BlobId>

Returns set of blob IDs that were a result of an oracle call.

pub fn messages(&self) -> &Vec<Vec<OutgoingMessage>>

Returns reference to the outgoing messages in the block.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ContainerType for Block

async fn resolve_field(&self, ctx: &Context<'_>) -> ServerResult<Option<Value>>

Resolves a field value and outputs it as a json value async_graphql::Value.

fn collect_all_fields<'a>( &'a self, ctx: &ContextBase<'a, &'a Positioned<SelectionSet>>, fields: &mut Fields<'a>, ) -> Result<(), ServerError>

where Self: Send + Sync,

Collect all the fields of the container that are queried in the selection set.

fn find_entity( &self, _: &ContextBase<'_, &Positioned<Field>>, _params: &ConstValue, ) -> impl Future<Output = Result<Option<ConstValue>, ServerError>> + Send

Find the GraphQL entity with the given name from the parameter.

impl Debug for Block

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Block

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl From<Block> for ExecutedBlock

fn from(block: Block) -> Self

Converts to this type from the input type.

impl Hash for Block

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl OutputType for Block

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, ctx: &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>

Introspection type name

impl PartialEq for Block

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Block

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl<'de> BcsHashable<'de> for Block

impl Eq for Block

impl ObjectType for Block
