Enum query_connector::WriteOperation

pub enum WriteOperation {
    Scalar(ScalarWriteOperation),
    Composite(CompositeWriteOperation),
}

A WriteExpression allows to express more complex operations on how the data is written, like field or inter-field arithmetic.

Variants

Scalar(ScalarWriteOperation)

Composite(CompositeWriteOperation)

Trait Implementations

impl Clone for WriteOperation

fn clone(&self) -> WriteOperation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WriteOperation

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

Formats the value using the given formatter.

impl From<(&SelectedField, PrismaValue)> for WriteOperation

fn from((selection, pv): (&SelectedField, PrismaValue)) -> Self

Converts to this type from the input type.

impl From<(&Zipper<CompositeFieldId>, PrismaValue)> for WriteOperation

fn from((_, pv): (&CompositeFieldRef, PrismaValue)) -> Self

Converts to this type from the input type.

impl From<(&Zipper<ScalarFieldId>, PrismaValue)> for WriteOperation

fn from((_, pv): (&ScalarFieldRef, PrismaValue)) -> Self

Converts to this type from the input type.

impl PartialEq for WriteOperation

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryInto<PrismaValue> for WriteOperation

type Error = ConnectorError

The type returned in the event of a conversion error.

fn try_into(self) -> Result<PrismaValue, Self::Error>

Performs the conversion.
