Enum BlockReference 

pub enum BlockReference {
    Finality(Finality),
    Height(u64),
    Hash(CryptoHash),
    SyncCheckpoint(SyncCheckpoint),
}

Reference to a specific block for RPC queries.

Every NEAR RPC query operates on state at a specific block.

Variants

Finality(Finality)

Query at latest block with specified finality.

Height(u64)

Query at specific block height.

Hash(CryptoHash)

Query at specific block hash.

SyncCheckpoint(SyncCheckpoint)

Query at a sync checkpoint (genesis or earliest available).

Implementations

impl BlockReference

pub fn final_() -> Self

Query at final block.

pub fn optimistic() -> Self

Query at optimistic (latest) block.

pub fn near_final() -> Self

Query at near-final block.

pub fn at_height(height: u64) -> Self

Query at specific height.

pub fn at_hash(hash: CryptoHash) -> Self

Query at specific hash.

pub fn genesis() -> Self

Query at genesis block.

pub fn earliest_available() -> Self

Query at earliest available block.

pub fn to_rpc_params(&self) -> Value

Convert to JSON for RPC requests.

Trait Implementations

impl Clone for BlockReference

fn clone(&self) -> BlockReference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockReference

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

Formats the value using the given formatter.

impl Default for BlockReference

fn default() -> Self

Returns the “default value” for a type.

impl From<CryptoHash> for BlockReference

fn from(hash: CryptoHash) -> Self

Converts to this type from the input type.

impl From<Finality> for BlockReference

fn from(f: Finality) -> Self

Converts to this type from the input type.

impl From<u64> for BlockReference

fn from(height: u64) -> Self

Converts to this type from the input type.

impl PartialEq for BlockReference

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