Enum InputFilter 

pub enum InputFilter {
    MaxLength(usize),
    CharClass(Arc<dyn Fn(char) -> bool + Send + Sync>),
}

One input filter — see the module-section doc above for why this is a separate concept from rosace_forms::Validator.

Variants

MaxLength(usize)

Reject any edit that would push the value’s CHAR count past n (truncates from the end).

CharClass(Arc<dyn Fn(char) -> bool + Send + Sync>)

Keep only characters for which the predicate returns true.

Implementations

impl InputFilter

pub fn max_length(n: usize) -> Self

pub fn char_class(f: impl Fn(char) -> bool + Send + Sync + 'static) -> Self

pub fn digits() -> Self

Convenience: digits only (a numeric field).

pub fn alphanumeric() -> Self

Convenience: letters and digits only.

Trait Implementations

impl Clone for InputFilter

fn clone(&self) -> InputFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.
