Trait NodeExt 

pub trait NodeExt: Node {
    // Provided methods
    fn query_service(
        &self,
        head: HeaderHash,
        id: ServiceId,

}

Provided Methods

fn query_service( &self, head: HeaderHash, id: ServiceId, ) -> impl Future<Output = Result<(Service, CodeInfo<CrateInfo>), Error>> + Send

fn wait_for_sync(&self) -> impl Future<Output = Result<(), Error>> + Send

fn lookup_anchor_block( &self, ) -> impl Future<Output = Result<BlockDesc, NodeError>> + Send

Returns lookup anchor block description.

This is the parent of the finalized block.

fn create_refine_context( &self, ) -> impl Future<Output = Result<(RefineContext, Slot), NodeError>> + Send

Create refine context from the current chain’s best block.

• Best block’s parent is used as an anchor.
• Finalized block is used as a lookup anchor.

Returns the resulting refine context and anchor slot.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
