Struct RangeRule 

pub struct RangeRule<T> {
    pub min: Option<T>,
    pub max: Option<T>,
    pub message: Option<String>,
}

Numeric range validation rule.

Validates that a number is within specified bounds.

Fields

min: Option<T>

Minimum value (inclusive)

max: Option<T>

Maximum value (inclusive)

message: Option<String>

Custom error message

Implementations

impl<T> RangeRule<T>

pub fn new(min: T, max: T) -> Self

Create a range rule with min and max bounds.

pub fn min(min: T) -> Self

Create a range rule with only a minimum.

pub fn max(max: T) -> Self

Create a range rule with only a maximum.

pub fn with_message(self, message: impl Into<String>) -> Self

Set a custom error message.

Trait Implementations

impl<T: Clone> Clone for RangeRule<T>

fn clone(&self) -> RangeRule<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for RangeRule<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for RangeRule<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for RangeRule<T>

fn eq(&self, other: &RangeRule<T>) -> 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<T> Serialize for RangeRule<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> ValidationRule<T> for RangeRule<T>

where T: PartialOrd + Display + Copy + Send + Sync + Debug + Serialize,

fn validate(&self, value: &T) -> Result<(), RuleError>

Validate the value against this rule.

fn rule_name(&self) -> &'static str

Get the rule name/code for error reporting.

fn default_message(&self) -> String

Get the default error message for this rule.
