Enum ArrayElement 

pub enum ArrayElement {
    SmallInt,
    Integer,
    BigInt,
    Real,
    Double,
    Boolean,
    Text,
    Uuid,
}

Element types valid inside SqlType::Array.

A strict subset of the SqlType catalogue: the value types Postgres supports as T[] and that umbral knows how to bind / decode through sqlx. Stays Copy so the outer SqlType::Array(ArrayElement) remains usable in const FIELDS slices.

Catalogue:

Variant	Postgres type	Rust inner type
SmallInt	int2[]	Vec<i16>
Integer	int4[]	Vec<i32>
BigInt	int8[]	Vec<i64>
Real	float4[]	Vec<f32>
Double	float8[]	Vec<f64>
Boolean	bool[]	Vec<bool>
Text	text[]	Vec<String>
Uuid	uuid[]	Vec<uuid::Uuid>

Other element types (Date / Time / Timestamptz / Json) land as follow-ons when there’s a real consumer; the binding semantics for chrono types as Postgres array elements need a deliberate pass.

Implementations

impl ArrayElement

pub fn to_sql_type(self) -> SqlType

Lift this element type back to its SqlType equivalent. Used when a per-element decision needs to dispatch through the same SqlType match the rest of umbral uses (e.g. picking a sea_query::ColumnType for the element).

Trait Implementations

impl Clone for ArrayElement

fn clone(&self) -> ArrayElement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ArrayElement

impl Debug for ArrayElement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ArrayElement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ArrayElement

impl PartialEq for ArrayElement

fn eq(&self, other: &ArrayElement) -> 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 ArrayElement

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
