Struct tinychain::txn::TxnId

pub struct TxnId { /* fields omitted */ }

Implementations

impl TxnId

pub fn new(time: NetworkTime) -> TxnId

pub fn next(&self) -> TxnId

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

pub fn prev(&self) -> TxnId

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

Parse this value using the given Decoder.

impl Hash for TxnId

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl<'en> IntoStream<'en> for TxnId

pub fn into_stream<E>(
    self,
    e: E
) -> Result<<E as Encoder<'en>>::Ok, <E as Encoder<'en>>::Error> where
    E: Encoder<'en>,
