Struct zebra_state::ChainTipBlock

pub struct ChainTipBlock {
    pub hash: Hash,
    pub height: Height,
    pub time: DateTime<Utc>,
    pub transactions: Vec<Arc<Transaction>>,
    pub transaction_hashes: Arc<[Hash]>,
    pub previous_block_hash: Hash,
}

A chain tip block, with precalculated block data.

Used to efficiently update ChainTipSender, LatestChainTip, and ChainTipChange.

Fields

hash: Hash

The hash of the best chain tip block.

height: Height

The height of the best chain tip block.

time: DateTime<Utc>

The network block time of the best chain tip block.

transactions: Vec<Arc<Transaction>>

The block transactions.

transaction_hashes: Arc<[Hash]>

The mined transaction IDs of the transactions in block, in the same order as block.transactions.

previous_block_hash: Hash

The hash of the previous block in the best chain. This block is immediately behind the best chain tip.

Note

If the best chain fork has changed, or some blocks have been skipped, this hash will be different to the last returned ChainTipBlock.hash.

Trait Implementations

impl Arbitrary for ChainTipBlock

type Parameters = (<Hash as Arbitrary>::Parameters, <Height as Arbitrary>::Parameters, <Vec<Arc<Transaction>> as Arbitrary>::Parameters, <Arc<[Hash]> as Arbitrary>::Parameters, <Hash as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<Hash as Arbitrary>::Strategy, <Height as Arbitrary>::Strategy, BoxedStrategy<DateTime<Utc>>, <Vec<Arc<Transaction>> as Arbitrary>::Strategy, <Arc<[Hash]> as Arbitrary>::Strategy, <Hash as Arbitrary>::Strategy), fn(_: (Hash, Height, DateTime<Utc>, Vec<Arc<Transaction>>, Arc<[Hash]>, Hash)) -> ChainTipBlock>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for ChainTipBlock

fn clone(&self) -> ChainTipBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChainTipBlock

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

Formats the value using the given formatter.

impl Display for ChainTipBlock

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

Formats the value using the given formatter.

impl From<CheckpointVerifiedBlock> for ChainTipBlock

fn from(CheckpointVerifiedBlock: CheckpointVerifiedBlock) -> Self

Converts to this type from the input type.

impl From<ContextuallyVerifiedBlock> for ChainTipBlock

fn from(contextually_valid: ContextuallyVerifiedBlock) -> Self

Converts to this type from the input type.

impl From<SemanticallyVerifiedBlock> for ChainTipBlock

fn from(prepared: SemanticallyVerifiedBlock) -> Self

Converts to this type from the input type.

impl<T> From<T> for ChainTipBlock

where T: Prepare,

fn from(block: T) -> Self

Converts to this type from the input type.

impl PartialEq for ChainTipBlock

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