Trait for Substrate client implementation

Provides a method to get events from the Substrate client. This trait is implemented for types that can retrieve events from a Substrate-based blockchain.

Required Methods

fn get_events_at<'life0, 'async_trait>( &'life0 self, block_hash: H256, ) -> Pin<Box<dyn Future<Output = Result<Events<SubstrateConfig>, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get events at a specific block hash

Arguments

• block_hash - The hash of the block to retrieve events from

Returns

• Result<subxt::events::Events<subxt::SubstrateConfig>, subxt::Error> - The events or an error

fn get_finalized_block<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Block<SubstrateConfig, OnlineClient<SubstrateConfig>>, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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.

impl SubstrateClientTrait for OnlineClient<SubstrateConfig>

Default implementation for Substrate client trait

Provides a default implementation for the Substrate client trait using the OnlineClient from the subxt crate.
