Struct SchemaProposal 

pub struct SchemaProposal { /* private fields */ }

Canonical current-form database-scoped proposal.

Implementations

impl SchemaProposal

pub fn try_compose( capabilities: Vec<SchemaCapability>, target_database: TargetDatabaseIdentity, submission_key: SchemaSubmissionKey, expected_head: ExpectedAcceptedHead, fragments: Vec<SchemaFragment>, assignments: Vec<EntityStoreAssignment>, removals: Vec<SchemaRemoval>, ) -> Result<SchemaProposal, SchemaContractError>

Compose the public transport form from already selected fragments.

This validates contract-local closure only. IcyDB still treats the result as untrusted and resolves target ownership, accepted references, capabilities, and catalog-native mutation semantics during application.

Errors

Returns a typed contract error for bounds, duplicate definitions, ambiguous routing, removal conflicts, or malformed nested data.

pub const fn version(&self) -> ProposalContractVersion

Return the contract version.

pub fn capabilities(&self) -> &[SchemaCapability]

Borrow required capabilities in canonical order.

pub const fn target_database(&self) -> TargetDatabaseIdentity

Return the target database identity.

pub const fn submission_key(&self) -> &SchemaSubmissionKey

Borrow the submission key.

pub const fn expected_head(&self) -> &ExpectedAcceptedHead

Borrow the optimistic accepted-head condition.

pub fn fragments(&self) -> &[SchemaFragment]

Borrow reusable fragments.

pub fn assignments(&self) -> &[EntityStoreAssignment]

Borrow canonical entity-to-store assignments.

pub fn removals(&self) -> &[SchemaRemoval]

Borrow explicit removals.

pub fn digest(&self) -> Result<SchemaProposalDigest, SchemaContractError>

Compute the canonical proposal digest.

Errors

Returns a typed encoding error if the proposal no longer satisfies the current bounded contract.
