Struct ProposalContext 

#[repr(C)]
pub struct ProposalContext {
    pub protocol: Protocol,
    pub proposer: ValidatorID,
    pub block_timepoint: TimePoint,
}

Inputs fixed before executing a candidate block.

Supplied by the coordinator when it asks the scheduler to build a proposal; the parent block is identified by the surrounding RPC. proposer and block_timepoint are copied into the resulting ProposalHeader.

Fields

protocol: Protocol

Network protocol version. ProposalHeader has no protocol field; the block’s version is ConsensusValue::protocol.

proposer: ValidatorID

Block proposer. Nodes missing block data fetch it from the proposer.

block_timepoint: TimePoint

The block’s timepoint, fixed by the coordinator before execution begins.
