Trait ConflictTarget 

pub trait ConflictTarget<T: Table>: Sealed { }

An ON CONFLICT target: one or more columns proven by T to belong to the table being inserted into, where a raw &[&str] would let a typo through to the database. Implemented for a bare Column<C> and for tuples of up to three; add arities as real schemas need them.

Dyn Compatibility

This trait is dyn compatible.

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