RestoredOptions

Struct RestoredOptions 

Source
struct RestoredOptions {
    class: Vec<String>,
    message: Option<String>,
    every_read: bool,
}
Expand description

The package’s condition classes and message for a pointer of the type restored from a saved session, #[externalptr(restored(class = "..." | ["...", "..."], message = "...", refuse = "every_read"))] (#1891, #1901). Each is optional; the derive emits TypedExternal::RESTORED_ERROR_CLASS / RESTORED_ERROR_MESSAGE for the ones given.

Fields§

§class: Vec<String>

The classes, in order, put in front of the miniextendr_restored* classes.

§message: Option<String>

The message, replacing miniextendr’s in both restored cases.

§every_read: bool

refuse = "every_read": the field methods refuse a restored pointer on the reads that never reach a field accessor too (names(), a name that is not a field), and .DollarNames() offers nothing for it (#1901). The derive emits the liveness check they call.
