pub fn min_length(value: usize) -> Self

Create a min length rule.

pub fn max_length(value: usize) -> Self

Create a max length rule.

pub fn pattern(pattern: impl Into<String>) -> Self

Create a pattern rule.

pub fn email() -> Self

Create an email rule.

Trait Implementations

impl Clone for ValidationRule

fn clone(&self) -> ValidationRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationRule

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValidationRule

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ValidationRule

fn eq(&self, other: &ValidationRule) -> 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.

impl Serialize for ValidationRule

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ValidationRule

impl StructuralPartialEq for ValidationRule
