Enum aptos_types::trusted_state::TrustedStateChange

source · [−]

pub enum TrustedStateChange<'a> {
    Version {
        new_state: TrustedState,
    },
    Epoch {
        new_state: TrustedState,
        latest_epoch_change_li: &'a LedgerInfoWithSignatures,

}

Expand description

TrustedStateChange is the result of attempting to ratchet to a new trusted state. In order to reduce redundant error checking, TrustedStateChange also contains references to relevant items used to ratchet us.

Variants

`Version`

Fields

new_state: TrustedState

We have a newer TrustedState but it’s still in the same epoch, so only the latest trusted version changed.

`Epoch`

Fields

new_state: TrustedState

latest_epoch_change_li: &'a LedgerInfoWithSignatures

We have a newer TrustedState and there was at least one epoch change, so we have a newer trusted version and a newer trusted validator set.

`NoChange`

The latest ledger info is at the same version as the trusted state and matches the hash.
