Trait HasUpserts 

pub trait HasUpserts {
    // Required method
    fn upserts_mut(&mut self) -> &mut Vec<ConflictClause>;
}

An INSERT’s upsert-clause list.

SQLite 3.35 and later accept several, tried in order:

INSERT … ON CONFLICT (a) DO UPDATE SET … ON CONFLICT DO NOTHING

with the rule that only the last may omit its conflict target. PostgreSQL has exactly one ON CONFLICT, which is why Conflict is a single slot and this is a list instead. The clause itself is core’s ConflictClause — SQLite’s ON CONFLICT (cols) [WHERE …] DO { NOTHING | UPDATE SET … [WHERE …] } is that shape exactly, minus the ON CONSTRAINT target, for which no mod is exported.

Required Methods

fn upserts_mut(&mut self) -> &mut Vec<ConflictClause>

The upsert clauses to modify.

Dyn Compatibility

This trait is dyn compatible.

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