Enum Validation

pub enum Validation {
    None,
    Valid,
    Invalid(String),
}

The status of validating data.

Variants

None

No validation has been performed yet.

This status represents that the data is still in its initial state, so errors should be delayed until it is changed.

Valid

The data is valid.

Invalid(String)

The data is invalid. The string contains a human-readable message.

Implementations

impl Validation

pub fn message<'a>(&'a self, hint: &'a str) -> &'a str

Returns the effective text to display along side the field.

When there is a validation error, it is returned, otherwise the hint is returned.

pub const fn is_error(&self) -> bool

Returns true if there is a validation error.

pub fn and(&self, other: &Self) -> Self

Returns the result of merging both validations.

Trait Implementations

impl Clone for Validation

fn clone(&self) -> Validation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Validation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Validation

fn default() -> Validation

Returns the “default value” for a type.

impl<T, E> IntoDynamic<Validation> for Dynamic<Result<T, E>>

where T: Send + 'static, E: Display + Send + 'static,

fn into_dynamic(self) -> Dynamic<Validation>

Returns self as a dynamic.

impl PartialEq for Validation

fn eq(&self, other: &Validation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
