Trait PostgresColumn 

pub trait PostgresColumn<'a>: SQLColumn<'a, PostgresValue<'a>> {
    const SERIAL: bool = false;
    const BIGSERIAL: bool = false;
    const GENERATED_IDENTITY: bool = false;
    const IDENTITY_ALWAYS: bool = true;
}

Provided Associated Constants

const SERIAL: bool = false

const BIGSERIAL: bool = false

const GENERATED_IDENTITY: bool = false

const IDENTITY_ALWAYS: bool = true

true = GENERATED ALWAYS AS IDENTITY, false = GENERATED BY DEFAULT AS IDENTITY. Only meaningful when GENERATED_IDENTITY is true.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
