Enum UtcScheme 

#[non_exhaustive]
pub enum UtcScheme {
    Ntp,
    Sntp,
    HttpHead,
    HttpXsdate,
    HttpIso,
    HttpNtp,
    Direct,
    Unknown,
}

A UTCTiming scheme (Table 35).

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.

Ntp

NTP servers; not acted on (no UDP in a sans-IO core).

Sntp

SNTP servers; not acted on.

HttpHead

HEAD, read the Date header.

HttpXsdate

GET, body is an xs:dateTime.

HttpIso

GET, body is an ISO 8601 time.

HttpNtp

GET, body is an NTP timestamp.

Direct

@value is the time.

Unknown

A scheme this core does not know.
