Module entity 

Entity traits for the Better Auth framework.

These traits define the interface that entity types must implement. The framework accesses entity fields through these trait methods, allowing users to define their own entity structs with custom field names and extra fields.

Use #[derive(AuthUser)] etc. from better-auth-derive to auto-implement these traits, or implement them manually.

Meta traits

Each entity trait has a corresponding Auth*Meta trait (e.g., AuthUserMeta) that provides table and column name mappings for SQL generation. The derive macros automatically implement both the entity trait and the meta trait.

If you implement entity traits manually (without derive macros), you must also implement the corresponding Auth*Meta trait. An empty impl block is sufficient to get the default column/table names:

impl AuthUserMeta for MyUser {}   // uses default column names
impl AuthSessionMeta for MySession {}
