Trait Implementations

impl Clone for ColumnRef

fn clone(&self) -> ColumnRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnRef

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

Formats the value using the given formatter.

impl From<ColumnRef> for SimpleExpr

fn from(col: ColumnRef) -> SimpleExpr

Converts to this type from the input type.

impl IntoColumnRef for ColumnRef

fn into_column_ref(self) -> ColumnRef

impl PartialEq for ColumnRef

fn eq(&self, other: &ColumnRef) -> 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 PgExpr for ColumnRef

fn concatenate<T>(self, right: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express an postgres concatenate (||) expression.

fn concat<T>(self, right: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Alias of PgExpr::concatenate

fn matches<T>(self, expr: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express an postgres fulltext search matches (@@) expression.

fn contains<T>(self, expr: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express an postgres fulltext search contains (@>) expression.

fn contained<T>(self, expr: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express an postgres fulltext search contained (<@) expression.

fn ilike<L>(self, like: L) -> SimpleExpr

where L: IntoLikeExpr,

Express a ILIKE expression.

fn not_ilike<L>(self, like: L) -> SimpleExpr

where L: IntoLikeExpr,

Express a NOT ILIKE expression

fn get_json_field<T>(self, right: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express a postgres retrieves JSON field as JSON value (->).

fn cast_json_field<T>(self, right: T) -> SimpleExpr

Express a postgres retrieves JSON field and casts it to an appropriate SQL type (->>).

impl SqliteExpr for ColumnRef

fn glob<T>(self, right: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express an sqlite GLOB operator.

fn matches<T>(self, right: T) -> SimpleExpr
