Get information identifying a Snapshot.

If the given snapshot is known to the database, this function returns

The block height at which the snapshot was created

impl<Mode> Transaction<Mode>

pub async fn load_header<Types: NodeType>( &mut self, id: impl Into<BlockId<Types>> + Send, ) -> QueryResult<Header<Types>>

Load a header from storage.

This function is similar to AvailabilityStorage::get_header, but

does not require the QueryablePayload<Types> bound that that trait impl does
makes it easier to specify types since the type parameter is on the function and not on a trait impl
allows type conversions for the id parameter

This more ergonomic interface is useful as loading headers is important for many SQL storage functions, not just the AvailabilityStorage interface.
