Client implementation for the ChainHeadApi RPC API.

Provided Methods

fn chain_head_unstable_header<'life0, 'async_trait>( &'life0 self, follow_subscription: String, hash: Hash, ) -> Pin<Box<dyn Future<Output = RpcResult<Option<String>>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Retrieves the header of a pinned block.

This method should be seen as a complement to chainHead_unstable_follow, allowing the JSON-RPC client to retrieve more information about a block that has been reported.

Use archive_unstable_header if instead you want to retrieve the header of an arbitrary block.

Unstable

This method is unstable and subject to change in the future.

fn chain_head_unstable_genesis_hash<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = RpcResult<String>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Get the chain’s genesis hash.

Unstable

This method is unstable and subject to change in the future.

fn chain_head_unstable_unpin<'life0, 'async_trait>( &'life0 self, follow_subscription: String, hash: Hash, ) -> Pin<Box<dyn Future<Output = RpcResult<()>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Unpin a block reported by the follow method.

Ongoing operations that require the provided block will continue normally.

Unstable

This method is unstable and subject to change in the future.

fn chain_head_unstable_follow<'life0, 'async_trait>( &'life0 self, with_runtime: bool, ) -> Pin<Box<dyn Future<Output = Result<Subscription<FollowEvent<Hash>>, Error>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Track the state of the head of the chain: the finalized, non-finalized, and best blocks.

Unstable

This method is unstable and subject to change in the future.

fn chain_head_unstable_body<'life0, 'async_trait>( &'life0 self, follow_subscription: String, hash: Hash, network_config: Option<NetworkConfig>, ) -> Pin<Box<dyn Future<Output = Result<Subscription<ChainHeadEvent<String>>, Error>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Retrieves the body (list of transactions) of a pinned block.

This method should be seen as a complement to chainHead_unstable_follow, allowing the JSON-RPC client to retrieve more information about a block that has been reported.

Use archive_unstable_body if instead you want to retrieve the body of an arbitrary block.

Unstable

This method is unstable and subject to change in the future.

fn chain_head_unstable_storage<'life0, 'async_trait>( &'life0 self, follow_subscription: String, hash: Hash, key: String, child_key: Option<String>, network_config: Option<NetworkConfig>, ) -> Pin<Box<dyn Future<Output = Result<Subscription<ChainHeadEvent<String>>, Error>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Return a storage entry at a specific block’s state.

Unstable

This method is unstable and subject to change in the future.

fn chain_head_unstable_call<'life0, 'async_trait>( &'life0 self, follow_subscription: String, hash: Hash, function: String, call_parameters: String, network_config: Option<NetworkConfig>, ) -> Pin<Box<dyn Future<Output = Result<Subscription<ChainHeadEvent<String>>, Error>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Call into the Runtime API at a specified block’s state.

Unstable

This method is unstable and subject to change in the future.

Object Safety

This trait is not object safe.
