Enum ChangeFreq 

#[non_exhaustive]
pub enum ChangeFreq {
    Always,
    Hourly,
    Daily,
    Weekly,
    Monthly,
    Yearly,
    Never,
}

How often a page is expected to change, as the sitemap protocol spells it.

An enum rather than a string so "weakly" is a compile error instead of a sitemap that search engines quietly ignore. Use str::parse when the value arrives as text.

Examples

use molt::sitemap::ChangeFreq;
assert_eq!(ChangeFreq::Weekly.as_str(), "weekly");
assert_eq!("monthly".parse::<ChangeFreq>(), Ok(ChangeFreq::Monthly));
assert!("weakly".parse::<ChangeFreq>().is_err());

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Always

always — changes on every access.

Hourly

hourly.

Daily

daily.

Weekly

weekly.

Monthly

monthly.

Yearly

yearly.

Never

never — archived content.
