Enum Operation 

pub enum Operation {
    Insert(Insert),
    DeleteByKey(DeleteByKey),
    FindPkByIndex(FindPkByIndex),
    GetByKey(GetByKey),
    QueryPk(QueryPk),
    QuerySql(QuerySql),
    Transaction(Transaction),
    UpdateByKey(UpdateByKey),
}

A single database operation to be executed by a driver.

Each variant maps to one logical database action. The query planner selects variants based on the driver’s Capability: SQL drivers receive QuerySql and Insert, while key-value drivers receive GetByKey, QueryPk, etc.

All operation types implement From<T> for Operation, so they can be converted with .into().

Examples

use toasty_core::driver::operation::{Operation, Transaction};

let op: Operation = Transaction::start().into();
assert!(!op.is_transaction_commit());

Variants

Insert(Insert)

Insert a new record. Contains a lowered stmt::Insert statement.

DeleteByKey(DeleteByKey)

Delete one or more records identified by primary key.

FindPkByIndex(FindPkByIndex)

Look up primary keys via a secondary index.

GetByKey(GetByKey)

Fetch one or more records by exact primary key match.

QueryPk(QueryPk)

Query a table with a primary key filter, optional secondary filtering, ordering, and pagination.

QuerySql(QuerySql)

Execute a raw SQL statement. Only sent to SQL-capable drivers.

Transaction(Transaction)

A transaction lifecycle operation (begin, commit, rollback, savepoint).

UpdateByKey(UpdateByKey)

Update one or more records identified by primary key.
