pub struct MigrationPlan<'a> { /* private fields */ }Expand description
An ordered sequence of migration steps computed by MigrationRegistry::plan.
Holds a reference to the registry’s migration list and the indices of the steps to apply, avoiding any copies of the migration objects.
Implementations§
Source§impl<'a> MigrationPlan<'a>
impl<'a> MigrationPlan<'a>
Sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true if no migration steps are needed (source == target version).
Sourcepub fn apply(&self, ctx: &mut MigrationContext) -> ServerResult<()>
pub fn apply(&self, ctx: &mut MigrationContext) -> ServerResult<()>
Apply all migration steps in order to the given context.
Stops and returns the first error encountered.
Sourcepub fn step_descriptions(&self) -> Vec<&str>
pub fn step_descriptions(&self) -> Vec<&str>
Return descriptions of each step in this plan for logging/audit.
