Struct StorageSettings 

pub struct StorageSettings {
    pub storage_v2: bool,
}

Storage configuration settings for this node.

Controls whether this node uses v2 storage layout (static files + RocksDB routing) or v1/legacy layout (everything in MDBX).

These should be set during init_genesis or init_db depending on whether we want dictate behaviour of new or old nodes respectively.

Fields

storage_v2: bool

Whether this node uses v2 storage layout.

When true, enables all v2 storage features:

• Receipts and transaction senders in static files
• History indices in RocksDB (accounts, storages, transaction hashes)
• Account and storage changesets in static files
• Hashed state tables as canonical state representation

When false, uses v1/legacy layout (everything in MDBX).

Implementations

impl StorageSettings

pub const fn bitflag_encoded_bytes() -> usize

Used bytes by StorageSettingsFlags

pub const fn bitflag_unused_bits() -> usize

Unused bits for new fields by StorageSettingsFlags

impl StorageSettings

pub const fn base() -> StorageSettings

Returns the default base StorageSettings.

pub const fn v2() -> StorageSettings

Creates StorageSettings for v2 nodes with all storage features enabled:

• Receipts and transaction senders in static files
• History indices in RocksDB (storages, accounts, transaction hashes)
• Account and storage changesets in static files
• Hashed state as canonical state representation

Use this when the --storage.v2 CLI flag is set.

pub const fn v1() -> StorageSettings

Creates StorageSettings for v1/legacy nodes.

This keeps all data in MDBX, matching the original storage layout.

pub const fn is_v2(&self) -> bool

Returns true if this node uses v2 storage layout.

pub const fn receipts_in_static_files(&self) -> bool

Whether receipts are stored in static files.

pub const fn transaction_senders_in_static_files(&self) -> bool

Whether transaction senders are stored in static files.

pub const fn storages_history_in_rocksdb(&self) -> bool

Whether storages history is stored in RocksDB.

pub const fn transaction_hash_numbers_in_rocksdb(&self) -> bool

Whether transaction hash numbers are stored in RocksDB.

pub const fn account_history_in_rocksdb(&self) -> bool

Whether account history is stored in RocksDB.

pub const fn use_hashed_state(&self) -> bool

Whether to use hashed state tables (HashedAccounts/HashedStorages) as the canonical state representation instead of plain state tables. Implied by v2 storage layout.

pub const fn any_in_rocksdb(&self) -> bool

Returns true if any tables are configured to be stored in RocksDB.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for StorageSettings

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<StorageSettings, Error>

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

fn arbitrary_take_rest( u: Unstructured<'arbitrary>, ) -> Result<StorageSettings, Error>

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 StorageSettings

fn clone(&self) -> StorageSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compact for StorageSettings

fn to_compact<B>(&self, buf: &mut B) -> usize

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.
