Implementations

impl IntegerField

pub fn new(name: String) -> IntegerField

Create a new IntegerField with the given name

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("age".to_string());
assert_eq!(field.name, "age");
assert!(!field.required);
assert_eq!(field.min_value, None);

pub fn required(self) -> IntegerField

Set the field as required

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("age".to_string()).required();
assert!(field.required);

pub fn with_min_value(self, min_value: i64) -> IntegerField

Set the minimum value for the field

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("age".to_string()).with_min_value(0);
assert_eq!(field.min_value, Some(0));

pub fn with_max_value(self, max_value: i64) -> IntegerField

Set the maximum value for the field

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("count".to_string()).with_max_value(100);
assert_eq!(field.max_value, Some(100));

pub fn with_label(self, label: impl Into<String>) -> IntegerField

Set the label for the field

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("age".to_string()).with_label("Age");
assert_eq!(field.label, Some("Age".to_string()));

pub fn with_help_text(self, help_text: impl Into<String>) -> IntegerField

Set the help text for the field

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("age".to_string()).with_help_text("Enter your age");
assert_eq!(field.help_text, Some("Enter your age".to_string()));

pub fn with_initial(self, initial: i64) -> IntegerField

Set the initial value for the field

Examples

use reinhardt_forms::fields::IntegerField;

let field = IntegerField::new("quantity".to_string()).with_initial(1);
assert_eq!(field.initial, Some(serde_json::json!(1)));
