Struct TrieChangeSetsEntry 

pub struct TrieChangeSetsEntry {
    pub nibbles: StoredNibblesSubKey,
    pub node: Option<BranchNodeCompact>,
}

Trie changeset entry representing the state of a trie node before a block.

nibbles is the subkey when used as a value in the changeset tables.

Fields

nibbles: StoredNibblesSubKey

The nibbles of the intermediate node

node: Option<BranchNodeCompact>

Node value prior to the block being processed, None indicating it didn’t exist.

Trait Implementations

impl Clone for TrieChangeSetsEntry

fn clone(&self) -> TrieChangeSetsEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compact for TrieChangeSetsEntry

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) -> (TrieChangeSetsEntry, &[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 Debug for TrieChangeSetsEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TrieChangeSetsEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TrieChangeSetsEntry

fn eq(&self, other: &TrieChangeSetsEntry) -> 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 Serialize for TrieChangeSetsEntry

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 Eq for TrieChangeSetsEntry

impl StructuralPartialEq for TrieChangeSetsEntry

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.
