Trait Implementations

impl Clone for PostgresDialect

fn clone(&self) -> PostgresDialect

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PostgresDialect

impl Debug for PostgresDialect

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Dialect for PostgresDialect

fn render_select_owned(&self, select: Select) -> Result<Sql>

Render an owned SELECT query into SQL, moving bound values out of the AST instead of cloning them. This is the primary rendering entry point used by the engine’s hot paths; dialects implement this.

fn render_insert_owned(&self, insert: Insert) -> Result<Sql>

Render an owned INSERT query into SQL, moving bound values out of the AST instead of cloning them.

fn render_update_owned(&self, update: Update) -> Result<Sql>

Render an owned UPDATE query into SQL, moving bound values out of the AST instead of cloning them.

fn render_delete_owned(&self, delete: Delete) -> Result<Sql>

Render an owned DELETE query into SQL, moving bound values out of the AST instead of cloning them.

fn supports_returning(&self) -> bool

Whether this dialect natively supports the RETURNING clause on INSERT, UPDATE, and DELETE statements.

fn render_select(&self, select: &Select) -> Result<Sql>

Render a borrowed SELECT query into SQL.

fn render_insert(&self, insert: &Insert) -> Result<Sql>

Render a borrowed INSERT query into SQL by cloning and delegating to Self::render_insert_owned.

fn render_update(&self, update: &Update) -> Result<Sql>

Render a borrowed UPDATE query into SQL by cloning and delegating to Self::render_update_owned.

fn render_delete(&self, delete: &Delete) -> Result<Sql>

Render a borrowed DELETE query into SQL by cloning and delegating to Self::render_delete_owned.
