Struct CausalReadOptions 

pub struct CausalReadOptions {
    pub preferred_region: Option<String>,
    pub deadline: Duration,
}

Options for a causal read route.

Fields

preferred_region: Option<String>

Region the caller prefers to read from (locality). When set, a healthy replica in this region is chosen as the wait target ahead of out-of-region replicas.

deadline: Duration

Upper bound on how long to wait for the target to catch up before falling back.

Implementations

impl CausalReadOptions

pub fn with_deadline(deadline: Duration) -> Self

Bounded wait with the given deadline and no region preference.

pub fn prefer_region(self, region: impl Into<String>) -> Self

Prefer reads from region.
