Struct CommitToken 

pub struct CommitToken { /* private fields */ }

A bookmark identifying a specific committed transaction in the master’s replication stream.

Port of com.sleepycat.je.CommitToken ({ repenvUUID, vlsn }).

Implementations

impl CommitToken

pub fn new(group: impl Into<String>, vlsn: u64) -> Option<Self>

Create a commit token for vlsn produced by replication group.

Port of new CommitToken(envUUID, commitVLSN.getSequence()) (MasterTxn.getCommitToken). Mirrors JE’s invariant that the VLSN must not be NULL (0): a token with no commit VLSN is meaningless, so returns None rather than minting a bogus bookmark.

pub fn group(&self) -> &str

The replication-group identity that produced this token.

Port of CommitToken.getRepenvUUID.

pub fn vlsn(&self) -> u64

The commit VLSN this token marks.

Port of CommitToken.getVLSN.

Trait Implementations

impl Clone for CommitToken

fn clone(&self) -> CommitToken

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CommitToken

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for CommitToken

impl Hash for CommitToken

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CommitToken

fn eq(&self, other: &CommitToken) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
