Implementations§

Source §

impl CatalogMigrationPlan

Source

pub const fn has_errors(&self) -> bool

Returns whether preflight found a condition that prevents writing.

Source

pub fn ensure_ready(&self) -> Result<()>

Rejects a plan that cannot be written safely.

§Errors

Returns an error if any schema conflicts or unresolved schemas remain. The error summarizes every schema conflict and unresolved schema.
