Implementations

impl FileField

pub fn new(name: String) -> Self

Create a new FileField

Examples

use reinhardt_forms::fields::FileField;

let field = FileField::new("upload".to_string());
assert_eq!(field.name, "upload");
assert_eq!(field.max_size, 10 * 1024 * 1024);

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

Set the maximum file size in bytes.

Examples

use reinhardt_forms::fields::FileField;

let field = FileField::new("upload".to_string()).with_max_size(5 * 1024 * 1024);
assert_eq!(field.max_size, 5 * 1024 * 1024);
