Struct TypeRegistrationOptions 

pub struct TypeRegistrationOptions {
    pub on_existing: OnExisting,
    pub revalidate: bool,
    pub dry_run: bool,
    pub migrations: Vec<MigrationSpec>,
}

Per-batch registration options.

Fields

on_existing: OnExisting

revalidate: bool

Admit a change the schemas cannot prove compatible when every stored row of the type still validates against the candidate.

This is deliberately a second, explicit ground for admission rather than a relaxation of the first: it is a statement about this tenant’s current rows, not about the accepted instance sets, and it costs a scan of the type bounded by type_update_max_rows.

dry_run: bool

Compute and report every verdict, write nothing.

migrations: Vec<MigrationSpec>

Payload migrations, at most one per type in the batch.

A migration is the third ground for admitting a change, and the only one that changes data: the steps are applied to every live row of the type, the result is validated against the candidate, and nothing is written unless every row passes. It requires a schema change to migrate towards — a migration on an unchanged type would be a data-editing API wearing a type endpoint’s clothes.
