Storage ChangeSet reader

Required Methods

fn storage_changeset( &self, block_number: BlockNumber, ) -> ProviderResult<Vec<(BlockNumberAddress, StorageEntry)>>

Iterate over storage changesets and return the storage state from before this block.

fn get_storage_before_block( &self, block_number: BlockNumber, address: Address, storage_key: B256, ) -> ProviderResult<Option<StorageEntry>>

Search the block’s changesets for the given address and storage key, and return the result.

Returns None if the storage slot was not changed in this block.

fn storage_changesets_range( &self, range: impl RangeBounds<BlockNumber>, ) -> ProviderResult<Vec<(BlockNumberAddress, StorageEntry)>>

Get all storage changesets in a range of blocks.

Provided Methods

fn storage_block_changeset( &self, block_number: BlockNumber, ) -> ProviderResult<Vec<StorageBeforeTx>>

Get storage changesets for a block as static-file rows.

Default implementation uses storage_changeset and maps to StorageBeforeTx.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
