Struct SchemaMigrationPlan 

pub struct SchemaMigrationPlan { /* private fields */ }

One canonical database-scoped coordinated migration plan.

Implementations

impl SchemaMigrationPlan

pub fn try_new( transitions: Vec<EntityMigration>, ) -> Result<SchemaMigrationPlan, SchemaContractError>

Construct, canonicalize, bound, and digest one coordinated plan.

Errors

Returns a typed migration or encoded-size error for an empty, duplicate, ambiguous, or oversized plan.

pub fn validate_target_fragment( &self, fragment: &SchemaFragment, ) -> Result<(), SchemaContractError>

Validate a complete authored target fragment against this migration plan.

Uses the proposal’s source-reference, closure and version rules without requiring runtime database identities, stores or an accepted head. This does not qualify the predecessor’s retained data or authorize migration.

Errors

Returns the proposal contract error for malformed inputs, missing target definitions, version gaps, or invalid rename/transform targets.

pub const fn program_version(&self) -> u16

Return the closed migration-program version.

pub fn transitions(&self) -> &[EntityMigration]

Borrow canonical entity transitions.

pub const fn digest(&self) -> SchemaMigrationPlanDigest

Return the exact canonical plan digest.
