Struct EventRecord 

pub struct EventRecord { /* private fields */ }

One serialized history line. Fields private: the only paths to a record are EventRecord::from_draft (append side) and EventRecord::parse_line (read side).

Implementations

impl EventRecord

pub fn moment(&self) -> Option<TimeMs>

This line’s own moment: Some(t) for a kind that records_a_moment, written at a version that measures it; None for every other line. A None on one of those four kinds means the moment was not measured, not that it took no time.

impl EventRecord

pub fn from_draft(draft: EventDraft, seq: Seq, prev: B3Hash) -> Self

Append-side assembly: the caller (a Ledger implementation) owns seq and prev; v is pinned to EVENT_LOG_V.

pub fn canonical_line(&self) -> Result<Vec<u8>, AxError>

The canonical bytes (no line terminator). The one byte producer library-wide; adapters append these bytes verbatim and hash exactly them for the next line’s prev.

pub fn parse_line(raw: &[u8]) -> Result<Self, AxError>

Read-side entrance: full field revalidation, fail-closed. Unknown kinds fail here; the ig:true skip belongs to replay, which probes the envelope before committing to a typed parse.

pub fn to_ref(&self) -> EventRef

Minting a reference requires holding a whole record (15.3-1): the append path holds what it just assembled, replay holds what it just verified. There is no third path.
