Struct StorageLayout 

pub struct StorageLayout {
    pub table: String,
    pub fields: Vec<LayoutField>,
}

Physical layout for one table, derived from schema metadata.

Fields

table: String

Table / collection name.

fields: Vec<LayoutField>

Ordered fields (includes id when present on the schema).

Implementations

impl StorageLayout

pub fn from_schema(schema: &Schema) -> Result<StorageLayout, Error>

Build layout from a full Schema.

Errors

Returns Error::Validation for unsafe identifiers or unknown field types.

pub fn from_registry_table(table: &str) -> Result<StorageLayout, Error>

Build layout from the global registry by table name.

Prefer {Model}Schema::full() + Self::from_schema when the type is known.

Errors

Returns Error::Internal when the table is not registered.

pub fn resolve_for_write( table: &str, content: &Value, ) -> Result<StorageLayout, Error>

Best-effort layout: registry schema when present, else dynamic fields from content.

Used by adapters on first write for non-schema (contract) tables.

Errors

Propagates identifier / type mapping failures.

pub fn from_content_keys( table: &str, content: &Value, ) -> Result<StorageLayout, Error>

Layout with id plus one field per top-level JSON key (JSON cell storage).

Errors

Returns Error::Validation for unsafe identifiers.

pub fn field_names(&self) -> Vec<&str>

Field names in layout order (including id).

pub fn data_fields(&self) -> impl Iterator<Item = &LayoutField>

Non-primary data fields.

pub fn to_ddl(&self, engine_id: &str) -> Result<String, Error>

Render create-table DDL (or structured JSON) for an engine id.

Errors

Returns Error::Validation for unknown engines or unsafe idents.

pub fn to_layout_json(&self) -> Result<Value, Error>

Structured JSON description of the layout (Redis/Mongo/Indra export).

Errors

Returns Error::Serialization on encode failure.
