Enum Timeout 

pub enum Timeout {
    Infinite,
    After(Duration),
}

A timeout that is either unbounded or a finite Duration.

FusionCache encodes “no timeout” as Timeout.InfiniteTimeSpan (a -1ms sentinel). Modelling that as a negative Duration is a footgun; an explicit two-variant enum makes “infinite” a first-class, unmistakable state and keeps every illegal negative-duration combination unrepresentable.

Variants

Infinite

Wait forever / never time out.

After(Duration)

Time out after the given finite duration.

Implementations

impl Timeout

pub fn from_option(duration: Option<Duration>) -> Self

Builds a timeout from an optional duration (None ⇒ Timeout::Infinite).

pub fn is_infinite(self) -> bool

true if this timeout never fires.

pub fn is_immediate(self) -> bool

true if this is a finite, zero-length timeout (fire immediately).

pub fn as_duration(self) -> Option<Duration>

The finite duration, or None when infinite.

pub fn min(self, other: Timeout) -> Timeout

Returns the shorter of two timeouts (infinite is treated as longest).
