Struct SlugValidator 

pub struct SlugValidator { /* private fields */ }

Validates that a string value is a valid URL slug.

A valid slug:

• Contains only lowercase ASCII letters (a-z), digits (0-9), hyphens (-), and underscores (_)
• Is non-empty
• Does not start or end with a hyphen

Examples

use reinhardt_forms::validators::SlugValidator;

let validator = SlugValidator::new();
assert!(validator.validate("my-article").is_ok());
assert!(validator.validate("page_1").is_ok());
assert!(validator.validate("-invalid").is_err());
assert!(validator.validate("has space").is_err());
assert!(validator.validate("").is_err());

Implementations

impl SlugValidator

pub fn new() -> Self

Creates a new SlugValidator with default settings.

Examples

use reinhardt_forms::validators::SlugValidator;

let validator = SlugValidator::new();
assert!(validator.validate("valid-slug").is_ok());

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

Sets a custom error message returned on validation failure.

Examples

use reinhardt_forms::validators::SlugValidator;

let validator = SlugValidator::new().with_message("Only lowercase letters, numbers, hyphens, and underscores are allowed");
assert!(validator.validate("Bad Slug!").is_err());

pub fn validate(&self, value: &str) -> FieldResult<()>

Validates the given string slice as a URL slug.

let validator = SlugValidator::new();
assert!(validator.validate("my-slug-123").is_ok());
assert!(validator.validate("trailing-").is_err());
assert!(validator.validate("-leading").is_err());
