Struct StorageShardedKey

pub struct StorageShardedKey {
    pub address: Address,
    pub sharded_key: ShardedKey<FixedBytes<32>>,
}

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 transition 0 to 200.

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

Fields

address: Address

Storage account address.

sharded_key: ShardedKey<FixedBytes<32>>

Storage slot with highest transition id.

Implementations

impl StorageShardedKey

pub const fn new( address: Address, storage_key: FixedBytes<32>, highest_block_number: u64, ) -> StorageShardedKey

Creates a new StorageShardedKey.

pub const fn last( address: Address, storage_key: FixedBytes<32>, ) -> StorageShardedKey

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.

Trait Implementations

impl AsRef<ShardedKey<FixedBytes<32>>> for StorageShardedKey

fn as_ref(&self) -> &ShardedKey<FixedBytes<32>>

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for StorageShardedKey

fn clone(&self) -> StorageShardedKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageShardedKey

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

Formats the value using the given formatter.

impl Decode for StorageShardedKey

fn decode(value: &[u8]) -> Result<StorageShardedKey, DatabaseError>

Decodes data coming from the database.

fn decode_owned(value: Vec<u8>) -> Result<Self, DatabaseError>

Decodes owned data coming from the database.

impl Default for StorageShardedKey

fn default() -> StorageShardedKey

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageShardedKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for StorageShardedKey

type Encoded = Vec<u8>

Encoded type.

fn encode(self) -> <StorageShardedKey as Encode>::Encoded

Encodes data going into the database.

impl Hash for StorageShardedKey

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StorageShardedKey

fn cmp(&self, other: &StorageShardedKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StorageShardedKey

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

impl PartialOrd for StorageShardedKey

fn partial_cmp(&self, other: &StorageShardedKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StorageShardedKey

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

Layout

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.
