Struct ChangeLogSample 

pub struct ChangeLogSample {
    pub object_type: String,
    pub modification_type: String,
    pub duration_ms: Option<i32>,
    pub duration_calc_version: Option<i64>,
    pub created_at_epoch: f64,
    pub object_id: Option<String>,
    pub trace_id: Option<String>,
}

One change-log row, projected to the columns perf analysis needs.

duration_ms is NULL for cooperative external producers (no FraiseQL request clock); duration_calc_version is the data-quality marker (extra_metadata->>'duration_calc_version') used to refuse mixing pre-fix rows with the wall-clock-correct ones — see fraiseql_db::changelog::DURATION_CALC_VERSION.

Fields

object_type: String

Entity type the mutation touched (object_type).

modification_type: String

INSERT / UPDATE / DELETE / CUSTOM.

duration_ms: Option<i32>

Wall-clock duration in milliseconds; None for non-executor producers.

duration_calc_version: Option<i64>

extra_metadata->>'duration_calc_version'; None when unmarked (legacy).

created_at_epoch: f64

EXTRACT(EPOCH FROM created_at) — seconds since the Unix epoch.

object_id: Option<String>

The changed entity’s id (object_id::text); None when absent.

trace_id: Option<String>

W3C trace id, when populated.

Trait Implementations

impl Clone for ChangeLogSample

fn clone(&self) -> ChangeLogSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeLogSample

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

Formats the value using the given formatter.

impl PartialEq for ChangeLogSample

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