Trait sp_consensus::block_validation::BlockAnnounceValidator

pub trait BlockAnnounceValidator<B: Block> {
    fn validate(
        &mut self, 
        header: &B::Header, 
        data: &[u8]
    ) -> Pin<Box<dyn Future<Output = Result<Validation, Box<dyn Error + Send>>> + Send>>;
}

Type which checks incoming block announcements.

Required methods

fn validate(
    &mut self,
    header: &B::Header,
    data: &[u8]
) -> Pin<Box<dyn Future<Output = Result<Validation, Box<dyn Error + Send>>> + Send>>

Validate the announced header and its associated data.

Note

Returning Validation::Failure will lead to a decrease of the peers reputation as it sent us invalid data.

The returned future should only resolve to an error iff there was an internal error validating the block announcement. If the block announcement itself is invalid, this should always return Validation::Failure.
