Module mz_compute_client::controller::error
source · Expand description
Errors returned by the compute controller.
The guiding principle for error handling in the compute controller is that each public method
should return an error type that defines exactly the error variants the method can return, and
no additional ones. This precludes the usage of a single ComputeControllerError enum that
simply includes the union of all error variants the compute controller can ever return (and
possibly some internal ones that are never returned to external callers). Instead, compute
controller methods return bespoke error types that serve as documentation for the failure modes
of each method and make it easy for callers to ensure that all possible errors are handled.
Structs§

Constants§
