pub fn raw_sql(self, raw_sql: impl Into<String>) -> Self

pub fn raw_sql_search_criteria(self, raw_sql: impl Into<String>) -> Self

pub fn object_group_by( self, property_name: impl Into<String>, storage_field: impl Into<String>, query: SelectQuery, ) -> Self

pub fn child_enhancement(self, query: SelectQuery) -> Self

pub fn relation(self, name: impl Into<String>) -> Self

pub fn relation_query(self, name: impl Into<String>, query: SelectQuery) -> Self

pub fn limit(self, limit: u64) -> Self

pub fn hard_limit(self, hard_limit: u64) -> Self

Override the outer materialized-list ceiling. Most callers should keep 10,000.

pub fn prepare_for_list(self) -> Result<Self, String>

Apply and validate list-materialization limits. This is intentionally not used by streaming execution.

pub fn offset(self, offset: u64) -> Self

pub fn page(self, offset: u64, limit: u64) -> Self

pub fn partition_by(self, field: impl Into<String>) -> Self

Scope pagination to each distinct value of field.

Relation loading sets this automatically. Most application queries should use a generated relation selector instead of calling this method directly.

pub fn stream(self, chunk_size: usize) -> Self

Enable streaming mode with the given chunk size. When streaming, rows are fetched and enhanced in batches rather than all at once.

pub fn stream_default(self) -> Self

Enable streaming mode with default chunk size (1000).
