The minimum viable model interface shared by RustRails model types.

Required Methods

fn new() -> Self

Creates a new instance with default values.

fn errors(&self) -> &Errors

Returns the model’s current error collection.

fn errors_mut(&mut self) -> &mut Errors

Returns the mutable error collection for validation updates.

Provided Methods

fn initialize(attrs: HashMap<String, Value>) -> Result<Self, AttributeError>

Creates a new instance and applies the provided attributes.

fn is_valid(&self) -> bool

Returns true when the model considers itself valid.

fn is_invalid(&self) -> bool

Returns true when the model considers itself invalid.

fn validate(&mut self) -> bool

Validates the model and updates its error collection.

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.
