Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ColumnTrait for Column

type EntityName = Entity

The entity this column belongs to.

fn def(&self) -> ColumnDef

SQL type and constraints attached to this column.

fn enum_type_name(&self) -> Option<&'static str>

If the column maps to a database ENUM, the enum’s type name. Returns None for non-enum columns.

fn select_as(&self, expr: Expr) -> SimpleExpr

Apply the standard SELECT-side cast for this column. By default, enum columns are cast to text; non-enum columns are returned as-is.

fn save_as(&self, val: Expr) -> SimpleExpr

Apply the standard write-side cast: convert text into the database’s enum type for enum columns, return as-is otherwise.

fn json_key(&self) -> &'static str

Available on crate feature with-json only.

JSON key used for this column when (de)serializing the model.

fn entity_name(&self) -> DynIden

Table iden of the entity this column belongs to.

fn as_column_ref(&self) -> (DynIden, DynIden)

Fully-qualified (table, column) reference, used when building expressions that need to disambiguate columns across joined tables.

fn eq<V>(&self, v: V) -> Expr

where V: Into<Value>,

Perform equality against a Value. None will be converted to IS NULL.

fn ne<V>(&self, v: V) -> Expr

where V: Into<Value>,

Perform inequality against a Value. None will be converted to IS NOT NULL.

fn gt<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn gte<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn lt<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn lte<V>(&self, v: V) -> Expr

where V: Into<Value>,

fn between<V>(&self, a: V, b: V) -> Expr

where V: Into<Value>,

fn not_between<V>(&self, a: V, b: V) -> Expr

where V: Into<Value>,

fn like<T>(&self, s: T) -> Expr

where T: IntoLikeExpr,

fn not_like<T>(&self, s: T) -> Expr

where T: IntoLikeExpr,

fn ilike<T>(&self, s: T) -> Expr

where T: IntoLikeExpr,

Postgres Only.

fn not_ilike<T>(&self, s: T) -> Expr

where T: IntoLikeExpr,

Postgres Only.

fn starts_with<T>(&self, s: T) -> Expr

where T: Into<String>,

This is a simplified shorthand for a more general like method. Use like if you need something more complex, like specifying an escape character.

fn ends_with<T>(&self, s: T) -> Expr

where T: Into<String>,

This is a simplified shorthand for a more general like method. Use like if you need something more complex, like specifying an escape character.

fn contains<T>(&self, s: T) -> Expr

where T: Into<String>,

This is a simplified shorthand for a more general like method. Use like if you need something more complex, like specifying an escape character.

fn max(&self) -> Expr

See also SeaQuery’s method with same name.

fn min(&self) -> Expr

See also SeaQuery’s method with same name.

fn sum(&self) -> Expr

See also SeaQuery’s method with same name.

fn avg(&self) -> Expr

See also SeaQuery’s method with same name.

fn count(&self) -> Expr

See also SeaQuery’s method with same name.

fn is_null(&self) -> Expr

See also SeaQuery’s method with same name.

fn is_not_null(&self) -> Expr

See also SeaQuery’s method with same name.

fn if_null<V>(&self, v: V) -> Expr

where V: Into<Value>,

Provide fallback value if the column is null (null coalescing)

fn is_in<V, I>(&self, v: I) -> Expr

where V: Into<Value>, I: IntoIterator<Item = V>,

fn is_not_in<V, I>(&self, v: I) -> Expr

where V: Into<Value>, I: IntoIterator<Item = V>,

fn eq_any<V, I>(&self, v: I) -> Expr

where V: Into<Value> + NotU8, I: IntoIterator<Item = V>,

Available on crate feature postgres-array only.

Postgres only.

fn ne_all<V, I>(&self, v: I) -> Expr

where V: Into<Value> + NotU8, I: IntoIterator<Item = V>,

Available on crate feature postgres-array only.

Postgres only. Opposite of eq_any (equivalent to is_not_in).

fn in_subquery(&self, s: SelectStatement) -> Expr

fn not_in_subquery(&self, s: SelectStatement) -> Expr

fn into_returning_expr(self, db_backend: DbBackend) -> Expr
