Trait ExecutionDataProvider

pub trait ExecutionDataProvider: Send + Sync {
    // Required methods
    fn execution_outcome(&self) -> &ExecutionOutcome;
    fn block_hash(&self, block_number: BlockNumber) -> Option<BlockHash>;
}

Provides data required for post-block execution.

This trait offers methods to access essential post-execution data, including the state changes in accounts and storage, as well as block hashes for both the pending and canonical chains.

The trait includes:

• ExecutionOutcome - Captures all account and storage changes in the pending chain.
• Block hashes - Provides access to the block hashes of both the pending chain and canonical blocks.

Required Methods

fn execution_outcome(&self) -> &ExecutionOutcome

Return the execution outcome.

fn block_hash(&self, block_number: BlockNumber) -> Option<BlockHash>

Return block hash by block number of pending or canonical chain.

Implementations on Foreign Types

impl ExecutionDataProvider for ExecutionOutcome

fn block_hash(&self, _block_number: BlockNumber) -> Option<BlockHash>

Always returns None because we don’t have any information about the block header.

fn execution_outcome(&self) -> &ExecutionOutcome

impl<'a, T: 'a + ExecutionDataProvider + ?Sized> ExecutionDataProvider for &'a T

where &'a T: Send + Sync,

fn execution_outcome(&self) -> &ExecutionOutcome

fn block_hash(&self, block_number: BlockNumber) -> Option<BlockHash>

impl<T: ExecutionDataProvider + ?Sized> ExecutionDataProvider for Box<T>
