Trait Implementations

impl Clone for AlterSystemStatement

fn clone(&self) -> AlterSystemStatement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlterSystemStatement

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

Formats the value using the given formatter.

impl Default for AlterSystemStatement

fn default() -> AlterSystemStatement

Returns the “default value” for a type.

fn eq(&self, other: &AlterSystemStatement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToSql for AlterSystemStatement

fn fmt_sql(&self, f: &mut String, fmt: SqlFormat)

Format the type to a SQL string.

fn to_sql(&self) -> String

Convert the type to a SQL string.
