Struct ContainsRule 

pub struct ContainsRule {
    pub substring: String,
    pub case_insensitive: bool,
    pub message: Option<String>,
}

Contains validation rule - string must contain a substring.

Example

use skp_validator_rules::string::contains::ContainsRule;
use skp_validator_core::{Rule, ValidationContext};

let rule = ContainsRule::new("@");
let ctx = ValidationContext::default();

assert!(rule.validate("test@example.com", &ctx).is_ok());
assert!(rule.validate("testexample.com", &ctx).is_err());

Fields

substring: String

The substring to search for

case_insensitive: bool

Case insensitive matching

message: Option<String>

Custom error message
