Struct lowercase

Source
pub struct lowercase;
Expand description

Sanitizer converts to lowercase. Validator checks if only lowercase.

§Examples

An example of the lowercase validator.

use seventy::{builtins::string::*, seventy, Newtype};

#[seventy(sanitize(lowercase))]
pub struct SearchQuery(String);

// Converts uppercase characters to lowercase.
assert_eq!(
    SearchQuery::try_new("What is the SeVeNTy crate?!")
        .unwrap()
        .into_inner(),
    "what is the seventy crate?!"
);

An example of the lowercase sanitizer.

use seventy::{builtins::string::*, seventy, Newtype};

#[seventy(validate(lowercase))]
pub struct LowercaseString(String);

// Successfully constructed because the string is only lowercase.
assert!(LowercaseString::try_new("whisper").is_ok());

// Unsuccessfully constructed because the string is not only lowercase.
assert!(LowercaseString::try_new("Whisper").is_err());
