Implementations§

impl BinaryOperator

pub fn is_word_operator(&self) -> bool

Returns true if this operator is represented as a word (AND, OR, DIV) rather than a symbol (+, -, <, etc.)

Word operators require spaces around them in SQL, while symbolic operators do not (though spaces are optional).

Trait Implementations§

impl Clone for BinaryOperator

fn clone(&self) -> BinaryOperator

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for BinaryOperator

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

Formats the value using the given formatter. Read more

impl PartialEq for BinaryOperator

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

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

1.0.0 · Source§

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 BinaryOperator

fn to_sql(&self) -> String

Convert this AST node to a SQL string

impl Copy for BinaryOperator

impl Eq for BinaryOperator

impl StructuralPartialEq for BinaryOperator

Auto Trait Implementations§

impl Freeze for BinaryOperator

impl RefUnwindSafe for BinaryOperator
