Struct StoredSubNode

pub struct StoredSubNode {
    pub key: Vec<u8>,
    pub nibble: Option<u8>,
    pub node: Option<BranchNodeCompact>,
}

Walker sub node for storing intermediate state root calculation state in the database.

Fields

key: Vec<u8>

The key of the current node.

nibble: Option<u8>

The index of the next child to visit.

node: Option<BranchNodeCompact>

The node itself.

Trait Implementations

impl Clone for StoredSubNode

fn clone(&self) -> StoredSubNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compact for StoredSubNode

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) -> (StoredSubNode, &[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 StoredSubNode

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

Formats the value using the given formatter.

impl Default for StoredSubNode

fn default() -> StoredSubNode

Returns the “default value” for a type.

impl From<CursorSubNode> for StoredSubNode

fn from(value: CursorSubNode) -> Self

Converts to this type from the input type.

impl From<StoredSubNode> for CursorSubNode

Implements conversion from StoredSubNode to CursorSubNode.

fn from(value: StoredSubNode) -> Self

Converts a StoredSubNode into a CursorSubNode.

Extracts necessary values from the StoredSubNode and constructs a corresponding CursorSubNode.

impl PartialEq for StoredSubNode

fn eq(&self, other: &StoredSubNode) -> 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 Eq for StoredSubNode

impl StructuralPartialEq for StoredSubNode

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.
