Implementations

impl ChainTipState

pub async fn block_hash(&self, ctx: &Context<'_>) -> Result<&Option<CryptoHash>>

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

pub async fn num_incoming_bundles(&self, ctx: &Context<'_>) -> Result<&u32>

pub async fn num_operations(&self, ctx: &Context<'_>) -> Result<&u32>

pub async fn num_outgoing_messages(&self, ctx: &Context<'_>) -> Result<&u32>

impl ChainTipState

pub fn verify_block_chaining( &self, new_block: &ProposedBlock, ) -> Result<(), ChainError>

Checks that the proposed block is suitable, i.e. at the expected height and with the expected parent.

pub fn already_validated_block( &self, height: BlockHeight, ) -> Result<bool, ChainError>

Returns true if the validated block’s height is below the tip height. Returns an error if it is higher than the tip.

pub fn update_counters( &mut self, transactions: &[Transaction], messages: &[Vec<OutgoingMessage>], ) -> Result<(), ChainError>

Checks if the measurement counters would be valid.

Trait Implementations

impl Allocative for ChainTipState

fn visit<'allocative_a, 'allocative_b: 'allocative_a>( &self, visitor: &'allocative_a mut Visitor<'allocative_b>, )

impl Clone for ChainTipState

fn clone(&self) -> ChainTipState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ContainerType for ChainTipState

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 ChainTipState

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

Formats the value using the given formatter.

impl Default for ChainTipState

fn default() -> ChainTipState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChainTipState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl OutputType for ChainTipState

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>

fn qualified_type_name() -> String

Qualified typename.

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

impl PartialEq for ChainTipState

fn eq(&self, other: &ChainTipState) -> 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.
