Enum postgres_types::Kind

#[non_exhaustive]
pub enum Kind {
    Simple,
    Enum(Vec<String>),
    Pseudo,
    Array(Type),
    Range(Type),
    Domain(Type),
    Composite(Vec<Field>),
}

Represents the kind of a Postgres type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Simple

A simple type like VARCHAR or INTEGER.

Enum(Vec<String>)

An enumerated type along with its variants.

Pseudo

A pseudo-type.

Array(Type)

An array type along with the type of its elements.

Range(Type)

A range type along with the type of its elements.

Domain(Type)

A domain type along with its underlying type.

Composite(Vec<Field>)

A composite type along with information about its fields.
