Enum ModuleError 

pub enum ModuleError<DomainError, RuntimeError> {
    Domain(DomainError),
    Runtime(RuntimeError),
}

One Module operation failure with an explicit Domain/Runtime split.

Ordinary operations can return Result<T, DomainError> directly. Use this type only when Module code must deliberately surface an Adapter-specific runtime failure in addition to its Capability-defined Domain Errors.

Variants

Domain(DomainError)

An expected Capability-defined business rejection.

Runtime(RuntimeError)

An infrastructure or execution failure outside the Capability contract.

Implementations

impl<DomainError, RuntimeError> ModuleError<DomainError, RuntimeError>

pub const fn domain(error: DomainError) -> Self

Creates a Capability-defined Domain Error.

pub const fn runtime(error: RuntimeError) -> Self

Creates an Adapter-specific Runtime Error.

pub fn map_domain<Other>( self, map: impl FnOnce(DomainError) -> Other, ) -> ModuleError<Other, RuntimeError>

Maps the Domain Error while preserving the Runtime Error.
