AccountChange reader

Required Methods

fn account_block_changeset( &self, block_number: BlockNumber, ) -> ProviderResult<Vec<AccountBeforeTx>>

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

fn get_account_before_block( &self, block_number: BlockNumber, address: Address, ) -> ProviderResult<Option<AccountBeforeTx>>

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

Returns None if the account was not changed in this block.

fn account_changesets_range( &self, range: impl RangeBounds<BlockNumber>, ) -> ProviderResult<Vec<(BlockNumber, AccountBeforeTx)>>

Get all account changesets in a range of blocks.

Accepts any range type that implements RangeBounds<BlockNumber>, including:

• Range<BlockNumber> (e.g., 0..100)
• RangeInclusive<BlockNumber> (e.g., 0..=99)
• RangeFrom<BlockNumber> (e.g., 0..) - iterates until exhausted

If there is no start bound, 0 is used as the start block.

Returns a vector of (block_number, changeset) pairs.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
