Expand description

Defines the core interface for blockchain clients

This trait must be implemented by all blockchain-specific clients to provide standardized access to blockchain data and operations.

Required Methods§

Source

fn get_latest_block_number<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Retrieves the latest block number from the blockchain

§Returns
  • Result<u64, anyhow::Error> - The latest block number or an error
Source

fn get_blocks<'life0, 'async_trait>( &'life0 self, start_block: u64, end_block: Option<u64>, ) -> Pin<Box<dyn Future<Output = Result<Vec<BlockType>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Retrieves a range of blocks from the blockchain

§Arguments
  • start_block - The starting block number
  • end_block - Optional ending block number. If None, only fetches start_block
§Returns
  • Result<Vec<BlockType>, anyhow::Error> - Vector of blocks or an error
§Note

The implementation should handle cases where end_block is None by returning only the start_block data.

Provided Methods§

Source

fn get_contract_spec<'life0, 'life1, 'async_trait>( &'life0 self, _contract_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<ContractSpec, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieves the contract spec for a given contract ID

§Arguments
  • contract_id - The ID of the contract to retrieve the spec for
§Returns
  • Result<ContractSpec, anyhow::Error> - The contract spec or an error

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.
