Struct MigrationPlan 

pub struct MigrationPlan {
    pub from: OperationFormat,
    pub to: OperationFormat,
    pub steps: Vec<MigrationStep>,
}

Describes the work needed to move an op log from one canonical form to another. Built by plan_migration; consumed by apply_migration.

Fields

from: OperationFormat

to: OperationFormat

steps: Vec<MigrationStep>

Steps in topological order — every step’s parents have already appeared earlier in the list, so applying in order keeps the partial DAG self-consistent.

Implementations

impl MigrationPlan

pub fn is_no_op(&self) -> bool

true if every step’s old and new op_id agree — applying the plan would be a no-op. Note that from == to does not imply this: tests inject custom encoders that produce different bytes for the same source format, in which case from == to == V1 but the migration is meaningful.

pub fn mapping(&self) -> BTreeMap<OpId, OpId>

Old → new op_id mapping in deterministic order.

Trait Implementations

impl Clone for MigrationPlan

fn clone(&self) -> MigrationPlan

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MigrationPlan

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MigrationPlan

fn eq(&self, other: &MigrationPlan) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
