Client implementation for the ChainApi RPC API.

Provided Methods§

fn header<'life0, 'async_trait>( &'life0 self, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Option<Header>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Get header.

fn block<'life0, 'async_trait>( &'life0 self, hash: Option<Hash>, ) -> Pin<Box<dyn Future<Output = Result<Option<SignedBlock>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Get header and body of a block.

fn block_hash<'life0, 'async_trait>( &'life0 self, hash: Option<ListOrValue<NumberOrHex>>, ) -> Pin<Box<dyn Future<Output = Result<ListOrValue<Option<Hash>>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: Sync + 'async_trait,

Get hash of the n-th block in the canon chain.

By default returns latest block hash.

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

Get hash of the last finalized block in the canon chain.

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

All head subscription.

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

New head subscription.

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

Finalized head subscription.

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.
