Implementations

impl Builder

fn new(dialect: Dialect) -> Self

Starts one statement with an empty parameter list.

fn name(&self, value: &str) -> Result<String, DatabaseError>

Quotes a validated logical identifier using the target SQL dialect.

fn bind(&mut self, value: Value) -> String

Appends one bind value without interpolating it into SQL text.

fn bind_field( &mut self, field: &Field, value: Value, ) -> Result<String, DatabaseError>

Encodes a logical field value before binding it to the physical dialect.

fn bind_named_field( &mut self, declaration: &Entity, field: &str, value: Value, ) -> Result<String, DatabaseError>

Finds the declared field type for a parameterized comparison.

fn comparison_name( &self, declaration: &Entity, name: &str, ) -> Result<String, DatabaseError>

Resolves a comparison key without changing the projected app field.

fn filter( &mut self, declaration: &Entity, predicate: &Predicate, ) -> Result<String, DatabaseError>

Lowers a validated predicate recursively while preserving parameter order.

fn compare( &mut self, declaration: &Entity, field: &str, operator: &str, value: &Value, ) -> Result<String, DatabaseError>

Handles null equality with SQL null semantics.

fn combine( &mut self, declaration: &Entity, parts: &[Predicate], separator: &str, ) -> Result<String, DatabaseError>

Joins a bounded group of nested predicates.

fn finish(self, sql: String) -> Statement

Finishes a statement without altering its bind order.
