A signed block is a block with Justification ,i.e., a Grandpa finality proof. The interval at which finality proofs are provided is set via the the GrandpaConfig.justification_period in a node’s service.rs. The Justification may be None.

fn get_signed_block_by_num<'life0, 'async_trait>( &'life0 self, number: Option<Self::BlockNumber> ) -> Pin<Box<dyn Future<Output = Result<Option<SignedBlock<Self::Block>>>> + 'async_trait>>

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

fn get_finalized_block<'life0, 'async_trait>( &'life0 self ) -> Pin<Box<dyn Future<Output = Result<Option<SignedBlock<Self::Block>>>> + 'async_trait>>

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

Get the last finalized signed block.

fn get_signed_blocks<'life0, 'life1, 'async_trait>( &'life0 self, block_numbers: &'life1 [Self::BlockNumber] ) -> Pin<Box<dyn Future<Output = Result<Vec<SignedBlock<Self::Block>>>> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a vector containing the blocks with the block numbers given in the input parameter. If fetching any of the block fails then a Result::Err will be returned.
