Struct exonum::messages::Block

pub struct Block { /* fields omitted */ }

Information about a block.

Validation

The message is ignored if * its to field corresponds to a different node * the block, transaction and precommits fields cannot be parsed or verified

Processing

The block is added to the blockchain.

Generation

The message is sent as response to RequestBlock.

Methods
