Implementations

impl ImageField

pub fn new(name: String) -> Self

Create a new ImageField

Examples

use reinhardt_forms::fields::ImageField;

let field = ImageField::new("photo".to_string());
assert_eq!(field.name, "photo");
assert_eq!(field.max_size, 5 * 1024 * 1024);

pub fn with_max_size(self, max_size: u64) -> Self

Set the maximum file size in bytes.

Examples

use reinhardt_forms::fields::ImageField;

let field = ImageField::new("photo".to_string()).with_max_size(2 * 1024 * 1024);
assert_eq!(field.max_size, 2 * 1024 * 1024);
