Enum UpsertStyle 

pub enum UpsertStyle {
    OnConflict,
    OnDuplicateKey,
}

How a dialect expresses an upsert (INSERT … ON CONFLICT).

Postgres and SQLite use ON CONFLICT (...) clauses, while MySQL uses ON DUPLICATE KEY UPDATE / INSERT IGNORE.

Variants

OnConflict

Postgres / SQLite: ON CONFLICT (...) DO {NOTHING|UPDATE SET …}.

OnDuplicateKey

MySQL: ON DUPLICATE KEY UPDATE … and INSERT IGNORE.
