Struct Availability 

#[non_exhaustive]
pub struct Availability {
    pub available: bool,
    pub backend: String,
    pub reason: Option<String>,
}

Availability envelope — returned from every list-ish method so callers can branch on available instead of assuming a populated list.

Flatten caution. This struct is #[serde(flatten)]ed into every listing payload (see CalendarListing, ContactListing, etc.). Do not add fields with names that collide with payload fields. #[non_exhaustive] to keep future additions additive.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

available: bool

True if the backend returned real data.

backend: String

Backend that was attempted ("eventkit", "msgraph", "eds", …).

reason: Option<String>

When available is false, human-readable explanation.
