    pub value: HashBuilderValue,
    pub stack: Vec<RlpNode>,
    pub groups: Vec<TrieMask>,
    pub tree_masks: Vec<TrieMask>,
    pub hash_masks: Vec<TrieMask>,
    pub stored_in_database: bool,
}

The hash builder state for storing in the database. Check the reth-trie crate for more info on hash builder.

The current node value.

stack: Vec<RlpNode>

The builder stack.

groups: Vec<TrieMask>

Group masks.

tree_masks: Vec<TrieMask>

Tree masks.

hash_masks: Vec<TrieMask>

Hash masks.

stored_in_database: bool

Flag indicating if the current node is stored in the database.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for HashBuilderState

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

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

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

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>

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

impl Clone for HashBuilderState

fn clone(&self) -> HashBuilderState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compact for HashBuilderState

Available on crate feature 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) -> (Self, &[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 HashBuilderState

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

Formats the value using the given formatter.

impl Default for HashBuilderState

fn default() -> HashBuilderState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HashBuilderState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<HashBuilder> for HashBuilderState

fn from(state: HashBuilder) -> Self

Converts to this type from the input type.

impl From<HashBuilderState> for HashBuilder

fn from(state: HashBuilderState) -> Self

Converts to this type from the input type.

impl PartialEq for HashBuilderState

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for HashBuilderState

impl StructuralPartialEq for HashBuilderState

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.
