Trait AsFormField

pub trait AsFormField {
    type Type: FormField;

    // Required methods
    fn clean_value(field: &Self::Type) -> Result<Self, FormFieldValidationError>
       where Self: Sized;
    fn to_field_value(&self) -> String;

    // Provided method
    fn new_field(
        options: FormFieldOptions,
        custom_options: <Self::Type as FormField>::CustomOptions,
    ) -> Self::Type { ... }
}

A trait for types that can be used as form fields.

This trait uses FormField to define a type that can be used as a form field. It provides a way to clean the value of the field, which is used to validate the field’s value before converting to the final type.

Required Associated Types

type Type: FormField

The form field type associated with the field.

Required Methods

fn clean_value(field: &Self::Type) -> Result<Self, FormFieldValidationError>

where Self: Sized,

Validates the value of the field and converts it to the final type. This method should return an error if the value is invalid.

Errors

Returns an error if the value fails to validate or convert to the final type

fn to_field_value(&self) -> String

Returns self as a value that can be set with FormField::set_value.

Provided Methods

fn new_field( options: FormFieldOptions, custom_options: <Self::Type as FormField>::CustomOptions, ) -> Self::Type

Creates a new form field with the given options and custom options.

This method is used to create a new instance of the form field with the given options and custom options. The options are used to set the properties of the field, such as the ID and whether the field is required.

The custom options are unique to each field type and are used to set additional properties of the field.

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.

Implementations on Foreign Types

impl AsFormField for bool

Implementation of AsFormField for bool.

This implementation converts the string values “true”, “on”, and “1” to true, and “false”, “ off“, and “0” to false. It returns an error if the value is not one of these strings. If the field is required to be true by the field’s options, it will return an error if the value is false.
