Struct CallOptions 

#[non_exhaustive]
pub struct CallOptions {
    pub deadline: Option<Duration>,
    pub max_retries: Option<u32>,
    pub offline: bool,
}

How patient a caller is. The default is a batch caller’s: providers’ own policies, retries and all. Set on an engine view with Engine::with_options; views share the cache, pacing and requests in flight.

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.

deadline: Option<Duration>

Caps each provider’s overall deadline, retries included.

max_retries: Option<u32>

Caps each provider’s retries.

offline: bool

Answers from the cache only, however old; what it lacks fails as Error::Offline.
