Struct EpochInfoV1Entry 

Source 
pub struct EpochInfoV1Entry {
    pub last_checkpoint_summary: CertifiedCheckpointSummary,
    pub last_checkpoint_contents: CheckpointContents,
    pub end_of_epoch_tx_effects: TransactionEffects,

    pub next_epoch_start_system_state_objects: Vec<Vec<u8>>,
}
Expand description

Per-epoch entry of the snapshot EPOCH_INFO file. Every field is anchored to the certified last_checkpoint_summary.

Fields§

§last_checkpoint_summary: CertifiedCheckpointSummary

Certified summary of this epoch’s closing checkpoint — the signed anchor every other field is proven against.

§last_checkpoint_contents: CheckpointContents

Contents of that closing checkpoint; hash == last_checkpoint_summary’s content_digest.

§end_of_epoch_tx_effects: TransactionEffects

Effects of the epoch-change tx (the last tx of the closing checkpoint); its (transaction, effects) digest pair is the last entry of last_checkpoint_contents.

§end_of_epoch_tx_events: TransactionEvents

Events from the epoch-change tx (carries SystemEpochInfoEvent); hash == end_of_epoch_tx_effects.events_digest, or empty on safe-mode boundaries where that digest is None.

§next_epoch_start_system_state_objects: Vec<Vec<u8>>

Raw serialized bytes of system-state wrapper object and its inner system-state object as written by this boundary — the next epoch’s start state. Each object’s digest matches a written-object entry in end_of_epoch_tx_effects.
