Enum CastFunctionKind 

pub enum CastFunctionKind {
    WithFunction {
        function_name: ObjectName,
        argument_types: Vec<DataType>,
    },
    WithoutFunction,
    WithInout,
}

The function binding kind for a CREATE CAST statement.

Note: this is a PostgreSQL-specific construct.

Trait Implementations

impl Clone for CastFunctionKind

fn clone(&self) -> CastFunctionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CastFunctionKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CastFunctionKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CastFunctionKind

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

Formats the value using the given formatter.

impl Hash for CastFunctionKind

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 Ord for CastFunctionKind

fn cmp(&self, other: &CastFunctionKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CastFunctionKind

fn eq(&self, other: &CastFunctionKind) -> 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 PartialOrd for CastFunctionKind

fn partial_cmp(&self, other: &CastFunctionKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for CastFunctionKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Visit for CastFunctionKind

fn visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

Visit this node with the provided Visitor.

impl VisitMut for CastFunctionKind

fn visit<V: VisitorMut>(&mut self, visitor: &mut V) -> ControlFlow<V::Break>

Mutably visit this node with the provided VisitorMut.

impl Eq for CastFunctionKind
