Struct Change 

pub struct Change {
    pub operation: ChangeOp,
    pub table: String,
    pub id: Value,
    pub fields: Option<HashMap<String, Value>>,
}

A database-agnostic change event for incremental sync.

This type represents a change (INSERT/UPDATE/DELETE) from a source database in a shared IR that can be converted to any target database format.

Fields

operation: ChangeOp

The operation type (Create/Update/Delete)

table: String

The table name

id: Value

The record ID

fields: Option<HashMap<String, Value>>

Field values (None for Delete operations)

Implementations

impl Change

pub fn new( operation: ChangeOp, table: impl Into<String>, id: Value, fields: Option<HashMap<String, Value>>, ) -> Self

Create a new change.

pub fn create( table: impl Into<String>, id: Value, fields: HashMap<String, Value>, ) -> Self

Create a CREATE change.

pub fn update( table: impl Into<String>, id: Value, fields: HashMap<String, Value>, ) -> Self

Create an UPDATE change.

pub fn delete(table: impl Into<String>, id: Value) -> Self

Create a DELETE change.
