Struct UnpreservedItem 

#[non_exhaustive]
pub struct UnpreservedItem {
    pub table: String,
    pub column: String,
    pub reason: UnpreservedReason,
    pub detail: String,
}

One piece of source schema that Catalog::copy_table could not reproduce.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

table: String

The schema-qualified table the dropped element belonged to.

Reports are merged across tables when a whole database is copied (CopyTableReport::merge), so without this a bare column name is ambiguous: two tables each carrying a created_at default would produce two indistinguishable entries.

column: String

The column the dropped schema element belonged to.

Empty for a table-level element such as a constraint, which belongs to a set of columns rather than to one; see detail for those.

reason: UnpreservedReason

Why it could not be carried across.

detail: String

The offending source text, so the caller can reapply it by hand.
