Enum solana_sdk::commitment_config::CommitmentLevel

pub enum CommitmentLevel {
    Max,
    Recent,
    Root,
    Single,
    SingleGossip,
}

An attribute of a slot. It describes how finalized a block is at some point in time. For example, a slot is said to be at the max level immediately after the cluster recognizes the block at that slot as finalized. When querying the ledger state, use lower levels of commitment to report progress and higher levels to ensure state changes will not be rolled back.

Variants

Max

The highest slot having reached max vote lockout, as recognized by a supermajority of the cluster.

Recent

The highest slot of the heaviest fork. Ledger state at this slot is not derived from a finalized block, but if multiple forks are present, is from the fork the validator believes is most likely to finalize.

Root

The highest slot having reached max vote lockout.

Single

The highest slot having reached 1 confirmation.

SingleGossip

The highest slot having reached 1 confirmation via gossip votes; may occur before or after Single, depending on gossip traffic.
