Struct SchemaMigrationDraft 

pub struct SchemaMigrationDraft { /* private fields */ }

Trusted authoring input containing only context-free schema steps.

This type deliberately has no serialization implementation. Persisted bytes can only be produced after replay by build_verified_manifest.

Implementations

impl SchemaMigrationDraft

pub fn new<S>( id: MigrationId, parents: Vec<MigrationId>, steps: Vec<S>, ) -> Result<Self, Diagnostic>

where S: Into<MigrationStep>,

Construct a draft, canonicalizing its set-like parent order.

pub fn legacy_bridge( id: MigrationId, legacy_parents: Vec<LegacyMigrationReference>, legacy_applied_set: LegacyAppliedSetDigest, ) -> Result<Self, Diagnostic>

Construct the zero-operation legacy-frontier bridge draft.

The bridge is the only manifest that names legacy parents; it carries no steps and no canonical parents, so its verified source and target are the identical reconstructed legacy head.

pub const fn id(&self) -> &MigrationId

Return the compound migration identity.

pub fn parents(&self) -> &[MigrationId]

Return canonical-sorted parent identities.

pub fn steps(&self) -> &[MigrationStep]

Return ordered trusted schema steps.

pub fn legacy_parents(&self) -> &[LegacyMigrationReference]

Return canonical-sorted legacy frontier references (bridge only).

pub const fn legacy_applied_set(&self) -> Option<&LegacyAppliedSetDigest>

Return the complete released applied-set digest (bridge only).
