Struct CreateOperation 

pub struct CreateOperation<E: QueryEngine, M: Model> { /* private fields */ }

A create operation for inserting a new record.

Example

let user = client
    .user()
    .create(user::Create {
        email: "new@example.com".into(),
        name: Some("New User".into()),
    })
    .exec()
    .await?;

Implementations

impl<E: QueryEngine, M: Model + FromRow> CreateOperation<E, M>

pub fn new(engine: E) -> Self

Create a new Create operation.

pub fn set( self, column: impl Into<String>, value: impl Into<FilterValue>, ) -> Self

Set a column value.

pub fn set_many( self, values: impl IntoIterator<Item = (impl Into<String>, impl Into<FilterValue>)>, ) -> Self

Set multiple column values from an iterator.

pub fn select(self, select: impl Into<Select>) -> Self

Select specific fields to return.

pub fn with(self, nw: NestedWriteOp) -> Self

Queue a nested write to run alongside this create.

The parent INSERT and every queued nested op execute inside a single implicit transaction — any failure rolls back the parent INSERT too. Typical use is via the codegen-emitted per-relation helpers:

c.user().create()
    .set("email", "u@x.com")
    .with(user::posts::create(vec![
        vec![("title".into(), "p1".into())],
    ]))
    .exec().await?;

pub fn build_sql(&self, dialect: &dyn SqlDialect) -> (String, Vec<FilterValue>)

Build the SQL query.

pub async fn exec(self) -> QueryResult<M>

where M: Send + 'static + ModelWithPk,

Execute the create operation and return the created record.

When no nested writes have been queued via Self::with, this runs a single INSERT ... RETURNING (or equivalent) against the engine. When nested writes are queued, the whole operation is wrapped in a transaction — the parent INSERT runs first, then each nested op in order; if any nested op fails the parent insert is rolled back too.

The ModelWithPk bound on the transactional branch is what gives the nested-write executor the parent’s primary-key value to splice into child rows’ foreign-key columns.
