Struct ArchiveStorageEventItem 

pub struct ArchiveStorageEventItem<Hash> {
    pub key: Bytes,
    pub value: Option<Bytes>,
    pub hash: Option<Hash>,
    pub closest_descendant_merkle_value: Option<Bytes>,
    pub child_trie_key: Option<Bytes>,
}

A storage item returned from the ChainHeadRpcMethods::archive_unstable_storage() subscription.

Fields

key: Bytes

String containing the hexadecimal-encoded key of the storage entry.

value: Option<Bytes>

String containing the hexadecimal-encoded value of the storage entry. Returned when the request type is StorageQueryType::Value or StorageQueryType::DescendantsValues.

hash: Option<Hash>

String containing the hexadecimal-encoded hash of the storage entry. Returned when the request type is StorageQueryType::Hash or StorageQueryType::DescendantsHashes.

closest_descendant_merkle_value: Option<Bytes>

String containing the hexadecimal-encoded Merkle value of the closest descendant of key (including branch nodes). Returned when the request type is StorageQueryType::ClosestDescendantMerkleValue.

child_trie_key: Option<Bytes>

String containing the hexadecimal-encoded key of the child trie of the “default” namespace if the storage entry is part of a child trie. If the storage entry is part of the main trie, this field is not present.

Trait Implementations

impl<Hash> Clone for ArchiveStorageEventItem<Hash>

where Hash: Clone,

fn clone(&self) -> ArchiveStorageEventItem<Hash>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Hash> Debug for ArchiveStorageEventItem<Hash>

where Hash: Debug,

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

Formats the value using the given formatter.

impl<'de, Hash> Deserialize<'de> for ArchiveStorageEventItem<Hash>

where Hash: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<ArchiveStorageEventItem<Hash>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Hash> PartialEq for ArchiveStorageEventItem<Hash>

where Hash: PartialEq,

fn eq(&self, other: &ArchiveStorageEventItem<Hash>) -> 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.
