Struct StorageEntry

pub struct StorageEntry {
    pub key: FixedBytes<32>,
    pub value: Uint<256, 4>,
}

Account storage entry.

key is the subkey when used as a value in the StorageChangeSets table.

Fields

key: FixedBytes<32>

Storage key.

value: Uint<256, 4>

Value on storage key.

Implementations

impl StorageEntry

pub const fn new(key: FixedBytes<32>, value: Uint<256, 4>) -> StorageEntry

Create a new StorageEntry with given key and value.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for StorageEntry

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<StorageEntry, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest( u: Unstructured<'arbitrary>, ) -> Result<StorageEntry, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

impl Clone for StorageEntry

fn clone(&self) -> StorageEntry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compact for StorageEntry

fn to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

Takes a buffer which can be written to. Ideally, it returns the length written to.

fn from_compact(buf: &[u8], len: usize) -> (StorageEntry, &[u8])

Takes a buffer which can be read from. Returns the object and buf with its internal cursor advanced (eg..advance(len)).

fn specialized_to_compact<B>(&self, buf: &mut B) -> usize

where B: BufMut + AsMut<[u8]>,

“Optional”: If there’s no good reason to use it, don’t.

fn specialized_from_compact(buf: &[u8], len: usize) -> (Self, &[u8])

“Optional”: If there’s no good reason to use it, don’t.

impl Compress for StorageEntry

type Compressed = Vec<u8>

Compressed type.

fn compress_to_buf<B>(self, buf: &mut B)

where B: BufMut + AsMut<[u8]>,

Compresses data to a given buffer.

fn uncompressable_ref(&self) -> Option<&[u8]>

If the type cannot be compressed, return its inner reference as Some(self.as_ref())

fn compress(self) -> Self::Compressed

Compresses data going into the database.

impl Debug for StorageEntry

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

Formats the value using the given formatter.

impl Decompress for StorageEntry

fn decompress(value: &[u8]) -> Result<StorageEntry, DatabaseError>

Decompresses data coming from the database.

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

Decompresses owned data coming from the database.

impl Default for StorageEntry

fn default() -> StorageEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<(FixedBytes<32>, Uint<256, 4>)> for StorageEntry

fn from(_: (FixedBytes<32>, Uint<256, 4>)) -> StorageEntry

Converts to this type from the input type.

impl Ord for StorageEntry

fn cmp(&self, other: &StorageEntry) -> 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 StorageEntry

fn eq(&self, other: &StorageEntry) -> 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 StorageEntry

fn partial_cmp(&self, other: &StorageEntry) -> 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 StorageEntry

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.

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.
