Enum CastMethod 

pub enum CastMethod {
    Function {
        name: QualifiedName,
        arg_types: Vec<ColumnType>,
    },
    Inout,
    Binary,
}

The conversion mechanism for a CREATE CAST.

Variants

Function

WITH FUNCTION fn(argtypes) — a managed function.

arg_types is the recorded conversion-function signature (1–3 args: source[, int4, bool]).

Fields

name: QualifiedName

Schema-qualified function name.

arg_types: Vec<ColumnType>

Argument types of the conversion function.

Inout

WITH INOUT — uses the types’ I/O functions.

Binary

WITHOUT FUNCTION — binary-coercible; no function required.

Trait Implementations

impl Clone for CastMethod

fn clone(&self) -> CastMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CastMethod

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CastMethod

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CastMethod

impl PartialEq for CastMethod

fn eq(&self, other: &CastMethod) -> 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 Serialize for CastMethod

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
