Struct HistoryEntry 

pub struct HistoryEntry {
    pub id: HistoryEntryId,
    pub author: HistoryAuthor,
    pub entry_kind: EntryKind,
    pub artifact_kind: ArtifactKind,
    pub timestamp: SystemTime,
    pub summary: String,
    pub text_delta: Option<(usize, usize)>,
    pub diff_payload: Option<Vec<u8>>,
    pub redaction: Option<RedactionDisplay>,
    pub context: Option<ActionContext>,
}

Fields

id: HistoryEntryId

author: HistoryAuthor

entry_kind: EntryKind

Drives the row’s icon glyph and the [Revert] chip’s visibility (see EntryKind::is_revertible).

artifact_kind: ArtifactKind

timestamp: SystemTime

summary: String

e.g. “+12 -3 chars”, “Moved to Done”. Producer should keep it short — the row is ~40 px tall.

text_delta: Option<(usize, usize)>

None means “not a text edit, or not countable” — never (0, 0), because a group aggregating these must be able to tell “nothing moved” from “we do not know”, and report an aggregate only when every member reported one.

diff_payload: Option<Vec<u8>>

Opaque bytes for the scrubber to re-derive the artifact’s state at this tick; the widget never cracks them open. None when an entry (Govern ops, pure metadata edits) has no per-entry payload.

redaction: Option<RedactionDisplay>

None means “not redacted; render the summary as normal”.

context: Option<ActionContext>

Semantic provenance carried by an action. Legacy/direct CRDT edits leave this empty and retain their structural diff summary.

Implementations

impl HistoryEntry

pub fn is_revertible(&self) -> bool

Whether this row represents a reversible document mutation. Durable effect receipts share the activity timeline but describe external work; reverting their metadata would not undo that work and is never offered.

pub fn is_genesis(&self) -> bool

Whether this row is the document’s genesis: the version it was created as. It stays restorable, but nobody made it and its time is not when anyone did, so it is shown without an author or a time and never offered as a recent change.

pub fn is_effect_receipt(&self) -> bool

Whether this row is a durable effect receipt: external work recorded in the activity timeline rather than a document mutation.

Trait Implementations

impl Clone for HistoryEntry

fn clone(&self) -> HistoryEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistoryEntry

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

Formats the value using the given formatter.

impl PartialEq for HistoryEntry

fn eq(&self, other: &HistoryEntry) -> 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.
