Trait SchemaExport 

pub trait SchemaExport: LayoutContract {
    // Required method
    fn layout_manifest() -> LayoutManifest;

    // Provided methods
    fn layout_info() -> LayoutInfo { ... }
    fn field_map() -> &'static [FieldInfo] { ... }
    fn manager_metadata() -> ManagerMetadata { ... }
    fn schema_bundle() -> SchemaBundle { ... }
}

Trait for layout types that can export their full schema information.

This creates a single source of truth linking runtime layout contracts (discriminator, version, layout_id, size) with field-level metadata (names, offsets, sizes). The exported information powers:

• Manager metadata (on-chain or off-chain program inspection)
• IDL generation (Codama, Hopper IDL, client SDKs)
• Schema diff and migration safety checking
• Client code generation with typed field access

Implementors provide both a runtime-facing view (layout_info, field_map) and a higher-level schema manifest for richer tooling.

Required Methods

fn layout_manifest() -> LayoutManifest

Rich schema manifest for diffing, linting, and client generation.

Provided Methods

fn layout_info() -> LayoutInfo

Runtime header/layout identity.

fn field_map() -> &'static [FieldInfo]

Field-level wire map used by manager and client tooling.

fn manager_metadata() -> ManagerMetadata

Combined runtime metadata payload for manager-facing inspection.

fn schema_bundle() -> SchemaBundle

Combined runtime and manifest metadata payload.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
