Struct HashedStorage

pub struct HashedStorage {
    pub wiped: bool,
    pub storage: HashMap<FixedBytes<32>, Uint<256, 4>, FbBuildHasher<32>>,
}

Available on crate feature trie only.

Representation of in-memory hashed storage.

Fields

wiped: bool

Flag indicating whether the storage was wiped or not.

storage: HashMap<FixedBytes<32>, Uint<256, 4>, FbBuildHasher<32>>

Mapping of hashed storage slot to storage value.

Implementations

impl HashedStorage

pub fn new(wiped: bool) -> HashedStorage

Create new instance of HashedStorage.

pub fn is_empty(&self) -> bool

Check if self is empty.

pub fn from_iter( wiped: bool, iter: impl IntoIterator<Item = (FixedBytes<32>, Uint<256, 4>)>, ) -> HashedStorage

Create new hashed storage from iterator.

pub fn from_plain_storage<'a>( status: AccountStatus, storage: impl IntoIterator<Item = (&'a Uint<256, 4>, &'a Uint<256, 4>)>, ) -> HashedStorage

Create new hashed storage from account status and plain storage.

pub fn construct_prefix_set(&self) -> PrefixSetMut

Construct PrefixSetMut from hashed storage.

pub fn extend(&mut self, other: &HashedStorage)

Extend hashed storage with contents of other. The entries in second hashed storage take precedence.

pub fn into_sorted(self) -> HashedStorageSorted

Converts hashed storage into HashedStorageSorted.

Trait Implementations

impl Clone for HashedStorage

fn clone(&self) -> HashedStorage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<TX> DatabaseHashedStorage<TX> for HashedStorage

where TX: DbTx,

fn from_reverts( tx: &TX, address: Address, from: u64, ) -> Result<HashedStorage, DatabaseError>

Initializes HashedStorage from reverts. Iterates over storage reverts from the specified block up to the current tip and aggregates them into hashed storage in reverse.

impl Debug for HashedStorage

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

Formats the value using the given formatter.

impl Default for HashedStorage

fn default() -> HashedStorage

Returns the “default value” for a type.

impl PartialEq for HashedStorage

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

impl StructuralPartialEq for HashedStorage

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.
