Struct CommitLog 

pub struct CommitLog { /* private fields */ }

The actions this endpoint kept, and the index their queries read.

Implementations

impl CommitLog

pub fn new() -> CommitLog

An empty log: it is built as changes and commits arrive.

pub fn kept(&self, commit: &WorkspaceCommit) -> bool

Whether this endpoint kept commit already: a peer’s retry of an action the log holds changes nothing.

pub fn record(&mut self, commit: &WorkspaceCommit, facts: &[ChangeFact])

Keep commit and index the facts its changes tell: which resource each wrote, which action it belongs to. A fact the commit does not name is ignored, so a caller may hand every change it has.

pub fn history_of( &mut self, workspace: &str, app: &str, record: &str, resource: &str, limit: usize, ) -> Vec<CommitHistory>

Every action that wrote resource of app’s record in workspace, newest first, at most limit of them: that resource’s own index entry and the actions it names, never the workspace’s whole log.

pub fn history(&self, workspace: &str) -> Vec<CommitHistory>

Every action this endpoint kept in workspace, oldest first.

pub fn action_of( &mut self, workspace: &str, hash: &[u8; 32], ) -> Option<CommitHistory>

The whole action the change hash of workspace is part of: every unit and every change of it, so an undo of one change takes its action back whole. None for a change no action this endpoint kept names.
