Struct LoadBalancerBuilder 

Source 
pub struct LoadBalancerBuilder { /* private fields */ }
Expand description

Builder for the sub-pipeline within a .load_balance() … .end_load_balance() block.

Exposes the same step methods as RouteBuilder (to, process, filter, etc.) but NOT .build() and NOT .load_balance() (no nested load balancers).

Calling .end_load_balance() packages the sub-steps into a BuilderStep::LoadBalance and returns the parent RouteBuilder.

Implementations§

Source§

impl LoadBalancerBuilder

Source

pub fn round_robin(self) -> Self

Set the load balance strategy to round-robin (default).

Source

pub fn random(self) -> Self

Set the load balance strategy to random selection.

Source

pub fn weighted(self, weights: Vec<(String, u32)>) -> Self

Set the load balance strategy to weighted selection.

Each endpoint is assigned a weight that determines its probability of being selected.

Source

pub fn failover(self) -> Self

Set the load balance strategy to failover.

Exchanges are sent to the first endpoint; on failure, the next endpoint is tried.

Source

pub fn parallel(self, parallel: bool) -> Self

Enable or disable parallel execution of endpoints.

When enabled, all endpoints receive the exchange simultaneously. When disabled (default), only one endpoint is selected per exchange.

Source

pub fn end_load_balance(self) -> RouteBuilder

Close the load balance scope. Packages the accumulated sub-steps into a BuilderStep::LoadBalance and returns the parent RouteBuilder.
