Struct TableSchema 

pub struct TableSchema {
    pub name: String,
    pub columns: HashMap<String, ColumnType>,
    pub policies: HashMap<String, String>,
    pub foreign_keys: Vec<ForeignKey>,
    pub rls_enabled: bool,
    pub owner_column: Option<String>,
}

Table schema information with column types and relations

Fields

name: String

Table name.

columns: HashMap<String, ColumnType>

Column name → Column type (strongly-typed AST enum)

policies: HashMap<String, String>

Column name → Access Policy (Default: “Public”, can be “Protected”)

foreign_keys: Vec<ForeignKey>

Foreign key relationships to other tables

rls_enabled: bool

Whether this table has Row-Level Security enabled Auto-detected: table has tenant_id column, an owner <column> attribute, or explicit rls keyword.

owner_column: Option<String>

Owner column for user-scoped isolation (owner <column> table attribute).

Explicit by design: a column named seller_id or user_id is never inferred as an owner scope. Only this declaration makes with_rls inject <column> = app.current_user_id.

Implementations

impl TableSchema

pub fn has_column(&self, name: &str) -> bool

Check if column exists

pub fn column_type(&self, name: &str) -> Option<&ColumnType>

Get column type

pub fn primary_key_column(&self) -> &str

Get the primary key column name for this table.

Convention: returns "id" if it exists as a column. This is a single point of truth for PK resolution — when the schema parser is enhanced to track PK constraints, update this method.

Trait Implementations

impl Clone for TableSchema

fn clone(&self) -> TableSchema

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TableSchema

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
