Struct ExecutionServicesBuilder 

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

Builder for ExecutionServices.

The builder exposes blocking-pool options by delegating to BlockingExecutorServiceBuilder and CPU-pool options by delegating to RayonExecutorServiceBuilder. Tokio-backed domains are created with their default constructors because they do not currently expose custom builders.

Source

pub fn build(self) -> Result<ExecutionServices, ExecutionServicesBuildError>

Builds the configured execution-services facade.

§Returns

Ok(ExecutionServices) if the blocking and CPU domains build successfully.

§Errors

Returns ExecutionServicesBuildError if either the blocking or CPU domain rejects its builder configuration.
