Trait CopyTarget

pub trait CopyTarget {
    type Table: Table;
    type SqlType: SqlType;
}

Available on crate feature postgres_backend only.

A expression that could be used as target/source for COPY FROM and COPY TO commands

This trait is implemented for any table type and for tuples of columns from the same table

Required Associated Types

type Table: Table

The table targeted by the command

type SqlType: SqlType

The sql side type of the target expression

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.
