Struct PreviewRecord 

pub struct PreviewRecord {
    pub id: String,
    pub seq: u64,
    pub candidate_page_id: String,
    pub source_hash: Option<String>,
    pub output: Option<String>,
    pub output_hash: Option<String>,
    pub parent_revision: Option<String>,
    pub critiques: Vec<PreviewCritique>,
    pub timestamp_ms: Option<u128>,
}

A top-level preview-artifact record appended to previews.jsonl.

The caller is responsible for computing timestamp_ms (unix milliseconds), source_hash, output_hash, and output (the rendered file path) before calling append_preview. This module performs no clock reads.

Fields

id: String

Stable preview id (unique within a document’s previews log).

seq: u64

Monotonic sequence number within this log (0-based).

candidate_page_id: String

Id of the page this preview is a rendering of.

source_hash: Option<String>

Optional content hash of the source artifact consumed to produce this preview.

output: Option<String>

Optional output file path of the rendered preview.

output_hash: Option<String>

Optional content hash of the rendered output file.

parent_revision: Option<String>

Optional id of the parent revision this preview was derived from.

critiques: Vec<PreviewCritique>

Critique annotations attached to this preview.

timestamp_ms: Option<u128>

Unix timestamp in milliseconds at which the preview was produced.

Trait Implementations

impl Clone for PreviewRecord

fn clone(&self) -> PreviewRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreviewRecord

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PreviewRecord

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PreviewRecord

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

impl Serialize for PreviewRecord

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
