    pub entity: T,

Fields

entity: T

state: EntityState

original: Option<HashMap<String, DbValue>>

Snapshot taken when the entity was attached (for change detection).

modified_properties: Vec<String>

Field names that differ from original (populated by detect_changes). Empty when detect_changes hasn’t run or the entity was marked Modified directly via update(). Used by execute_updates to generate partial UPDATE statements (SET only dirty columns).

is_upsert: bool

When true, the entry is in Added state but should be saved via execute_upserts (INSERT … ON CONFLICT DO UPDATE) instead of a plain INSERT. Set by upsert().
