Struct casper_execution_engine::core::engine_state::step::StepRequest

pub struct StepRequest {
    pub pre_state_hash: Digest,
    pub protocol_version: ProtocolVersion,
    pub slash_items: Vec<SlashItem>,
    pub reward_items: Vec<RewardItem>,
    pub evict_items: Vec<EvictItem>,
    pub next_era_id: EraId,
    pub era_end_timestamp_millis: u64,
}

Representation of a step request.

Fields

pre_state_hash: Digest

State root hash.

protocol_version: ProtocolVersion

Protocol version for this request.

slash_items: Vec<SlashItem>

List of validators to be slashed.

A slashed validator is removed from the next validator set.

reward_items: Vec<RewardItem>

List of validators that will be rewarded.

evict_items: Vec<EvictItem>

List of validators to be evicted.

Compared to a slashing, evictions are deactivating a given validator, but his stake is unchanged. A further re-activation is possible.

next_era_id: EraId

Specifies which era validators will be returned based on next_era_id.

Intended use is to always specify the current era id + 1 which will return computed era at the end of this step request.

era_end_timestamp_millis: u64

Timestamp in milliseconds representing end of the current era.

Implementations

impl StepRequest

pub fn new( pre_state_hash: Digest, protocol_version: ProtocolVersion, slash_items: Vec<SlashItem>, reward_items: Vec<RewardItem>, evict_items: Vec<EvictItem>, next_era_id: EraId, era_end_timestamp_millis: u64 ) -> Self

Creates new step request.

pub fn slashed_validators(&self) -> Vec<PublicKey>

Returns list of slashed validators.

pub fn reward_factors(&self) -> Result<BTreeMap<PublicKey, u64>, Error>

Returns all reward factors.
