Trait Implementations

impl<E: Clone + EntityTrait> Clone for JsonColumn<E>

where E::Column: Clone,

fn clone(&self) -> JsonColumn<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + EntityTrait> Debug for JsonColumn<E>

where E::Column: Debug,

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

Formats the value using the given formatter.

impl<E: Hash + EntityTrait> Hash for JsonColumn<E>

where E::Column: Hash,

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<E: EntityTrait> Iden for JsonColumn<E>

fn quoted(&self) -> Cow<'static, str>

Return the to-be sanitized version of the identifier.

fn unquoted(&self) -> &str

Write a raw identifier string without quotes.

fn to_string(&self) -> String

A shortcut for writing an unquoted identifier into a String.

impl<E: EntityTrait> IntoSimpleExpr for JsonColumn<E>

fn into_simple_expr(self) -> Expr

Method to perform the conversion

impl<E: PartialEq + EntityTrait> PartialEq for JsonColumn<E>

where E::Column: PartialEq,

fn eq(&self, other: &JsonColumn<E>) -> 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<E: Copy + EntityTrait> Copy for JsonColumn<E>

where E::Column: Copy,

impl<E: Eq + EntityTrait> Eq for JsonColumn<E>

where E::Column: Eq,

impl<E: EntityTrait> StructuralPartialEq for JsonColumn<E>
