Struct FallbackClientBuilder 

Source 
pub struct FallbackClientBuilder<T> {
    fallback_delay: Option<Duration>,
    clients: Option<Vec<T>>,
}
Expand description

Builder for FallbackClient.

Fields§

§fallback_delay: Option<Duration>

Duration to wait on one client before starting a fallback request on the next.

When a fallback request is started, the original request will not be cancelled, and so the overall operation can complete if the original request completes shortly after the fallback request is spawned. However, in the event that the original request takes a very long time or does not complete at all, the fallback allows the overall request to complete without much delay.

§clients: Option<Vec<T>>

Ordered list of clients.

Requests to the FallbackClient will be tried on each client successively, falling back down the list until success.

Implementations§

impl<T> FallbackClientBuilder<T>

Source

pub fn fallback_delay(self, value: Duration) -> Self

Duration to wait on one client before starting a fallback request on the next.

When a fallback request is started, the original request will not be cancelled, and so the overall operation can complete if the original request completes shortly after the fallback request is spawned. However, in the event that the original request takes a very long time or does not complete at all, the fallback allows the overall request to complete without much delay.

Source

pub fn clients(self, value: Vec<T>) -> Self
