Trait sp_consensus::block_validation::BlockAnnounceValidator[][src]

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>>; }
Expand description

Type which checks incoming block announcements.

Required methods

Validate the announced header and its associated data.


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.
