Implementations

impl Field

pub fn new( name: Ident, field_type: FieldType, modifier: TypeModifier, attributes: Vec<Attribute>, span: Span, ) -> Field

Create a new field.

pub fn name(&self) -> &str

Get the field name as a string.

pub fn is_optional(&self) -> bool

Check if the field is optional.

pub fn is_list(&self) -> bool

Check if the field is a list.

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

Check if this field has a specific attribute.

pub fn get_attribute(&self, name: &str) -> Option<&Attribute>

Get an attribute by name.

pub fn is_id(&self) -> bool

Check if this is a primary key field.

pub fn is_unique(&self) -> bool

Check if this field has a unique constraint.

pub fn is_relation(&self) -> bool

Check if this is a relation field.

pub fn extract_attributes(&self) -> FieldAttributes

Extract structured field attributes.

pub fn with_documentation(self, doc: Documentation) -> Field

Set documentation.

pub fn with_enhanced_documentation(self, doc: EnhancedDocumentation) -> Field

Set enhanced documentation (with validation extraction).

pub fn with_validation(self, validation: FieldValidation) -> Field

Set validation rules.

pub fn add_validation_rule(&mut self, rule: ValidationRule)

Add a validation rule.

pub fn has_validation(&self) -> bool

Check if this field has any validation rules.

pub fn validation_rules(&self) -> &[ValidationRule]

Get all validation rules for this field.

pub fn is_validated_required(&self) -> bool

Check if this field is required (via validation).

pub fn extract_validation_from_attributes(&mut self)

Extract validation rules from @validate attributes.

This parses attributes like:

• @validate.email
• @validate.minLength(5)
• @validate.range(0, 100)

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Field

fn deserialize<__D>( __deserializer: __D, ) -> Result<Field, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Field

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

Formats the value using the given formatter.

impl PartialEq for Field

fn eq(&self, other: &Field) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Field

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
