Expand description

SQL template trait

Defines basic operations for rendering SQL from templates

Required Methods§

Source

fn render_sql_with_encode_placeholder_fn( self, f: Option<fn(usize, &mut String)>, sql_buffer: &mut String, ) -> Result<Option<DB::Arguments<'q>>, Error>

Provided Methods§

Source

fn render_sql(self) -> Result<(String, Option<DB::Arguments<'q>>), Error>

Renders SQL template and returns query string with parameters

Source

fn render_execute_able( self, sql_buffer: &'q mut String, ) -> Result<SqlTemplateExecute<'q, DB>, Error>

Renders SQL template and returns executable query result

Source

fn render_db_adapter_manager( self, sql_buff: &'q mut String, ) -> DBAdapterManager<'q, DB, Self>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
