Trait DatabaseEnum 

pub trait DatabaseEnum {
    const TYPE_NAME: &'static str;
    const VARIANTS: &'static [&'static str];
}

Closed metadata generated by crate::Enum for database-backed enums.

Implementations must use a single unqualified SQL type identifier and a non-empty, ordered list of unique labels. Blueprint::native_enum validates manually written implementations before emitting SQL.

Required Associated Constants

const TYPE_NAME: &'static str

PostgreSQL type identifier. MySQL/MariaDB use the labels inline.

const VARIANTS: &'static [&'static str]

Ordered wire labels used by DDL, SQLx codecs, Serde and Display.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
