Enum IsolationLevel 

pub enum IsolationLevel {
    Snapshot,
    ReadCommitted,
    Serializable,
}

MVCC isolation level requested by ExecuteCommand::Begin.

Mirrors mongreldb_core::txn::IsolationLevel one-to-one (Snapshot, ReadCommitted, Serializable). The protocol crate cannot depend on the core crate (the server wave depends on both), so the enum is duplicated here and converted at the service boundary.

Variants

Snapshot

Snapshot isolation: the transaction reads one consistent snapshot.

ReadCommitted

Read committed: each statement reads the latest committed state.

Serializable

Serializable: snapshot reads plus certification at commit.
