pub struct ContainsRule {
    pub needle: String,
    pub message: Option<String>,
}

Contains substring validation rule.

Fields

needle: String

The substring that must be present

message: Option<String>

Custom error message

Implementations

impl ContainsRule

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

Create a new contains rule.

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

Set a custom error message.

Trait Implementations

impl Clone for ContainsRule

fn clone(&self) -> ContainsRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContainsRule

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContainsRule

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ContainsRule> for SerializableRule

fn from(rule: ContainsRule) -> Self

Converts to this type from the input type.

impl PartialEq for ContainsRule

fn eq(&self, other: &ContainsRule) -> 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 ContainsRule

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ValidationRule<String> for ContainsRule

fn validate(&self, value: &String) -> 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.

impl ValidationRule<str> for ContainsRule

fn validate(&self, value: &str) -> 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.
