Struct tc_transact::TxnId

pub struct TxnId { /* fields omitted */ }

The unique ID of a transaction, used for identity and ordering.

Implementations

impl TxnId

pub fn new(time: NetworkTime) -> Self

Construct a new TxnId.

pub fn next(&self) -> Self

Return the next valid TxnId after this one (e.g. to construct a range).

pub fn prev(&self) -> Self

Return the last valid TxnId before this one (e.g. to construct a range).

pub fn time(&self) -> NetworkTime

Return the timestamp of this TxnId.

pub fn to_id(&self) -> Id

impl Eq for TxnId

impl FromStr for TxnId

type Err = TCError

fn from_str(s: &str) -> TCResult<TxnId>

Parses a string s to return a value of this type.

impl FromStream for TxnId

type Context = ()

The decoding context of this type, useful in situations where the stream to be decoded may be too large to hold in main memory.

fn from_stream<'life0, 'async_trait, D: Decoder>(

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,
