Struct PackedStorageTrieEntry 

pub struct PackedStorageTrieEntry {
    pub nibbles: PackedStoredNibblesSubKey,
    pub node: BranchNodeCompact,
}

Account storage trie node with packed nibble encoding (storage v2).

Same as StorageTrieEntry but uses PackedStoredNibblesSubKey (33 bytes) instead of StoredNibblesSubKey (65 bytes).

Fields

nibbles: PackedStoredNibblesSubKey

The nibbles of the intermediate node

node: BranchNodeCompact

Encoded node.

Trait Implementations

impl Clone for PackedStorageTrieEntry

fn clone(&self) -> PackedStorageTrieEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compact for PackedStorageTrieEntry

Available on crate features reth-codec only.

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) -> (PackedStorageTrieEntry, &[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 PackedStorageTrieEntry

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 PackedStorageTrieEntry

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

Formats the value using the given formatter.

impl Decompress for PackedStorageTrieEntry

fn decompress(value: &[u8]) -> Result<PackedStorageTrieEntry, DecompressError>

Decompresses data coming from the database.

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

Decompresses owned data coming from the database.

impl<'de> Deserialize<'de> for PackedStorageTrieEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PackedStorageTrieEntry

impl Ord for PackedStorageTrieEntry

fn cmp(&self, other: &PackedStorageTrieEntry) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to #147781)

Restrict a value to a certain range.

impl PartialEq for PackedStorageTrieEntry

fn eq(&self, other: &PackedStorageTrieEntry) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PackedStorageTrieEntry

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

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.

impl StructuralPartialEq for PackedStorageTrieEntry

impl ValueWithSubKey for PackedStorageTrieEntry

type SubKey = PackedStoredNibblesSubKey

fn get_subkey(&self) -> <PackedStorageTrieEntry as ValueWithSubKey>::SubKey

Extract the subkey from the value.

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.
