Struct StorageShardedKey 

pub struct StorageShardedKey {
    pub address: Address,
    pub sharded_key: ShardedKey<B256>,
}

Sometimes data can be too big to be saved for a single key. This helps out by dividing the data into different shards. Example:

Address | StorageKey | 200 -> data is from block 0 to 200.

Address | StorageKey | 300 -> data is from block 201 to 300.

Fields

address: Address

Storage account address.

sharded_key: ShardedKey<B256>

Storage slot with highest block number.

Implementations

impl StorageShardedKey

pub const fn new( address: Address, storage_key: B256, highest_block_number: BlockNumber, ) -> Self

Creates a new StorageShardedKey.

pub const fn last(address: Address, storage_key: B256) -> Self

Creates a new key with the highest block number set to maximum. This is useful when we want to search the last value for a given key.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
