Struct tc_transact::TxnId [−][src]
pub struct TxnId { /* fields omitted */ }
Expand description
The unique ID of a transaction, used for identity and ordering.
Implementations
Construct a new TxnId
.
Return the last valid TxnId before this one (e.g. to construct a range).
Return the timestamp of this TxnId
.
Trait Implementations

and other
values if one exists. Read more
