NeverFail

Struct NeverFail

pub struct NeverFail;

Expand description

Policy that never injects a failure — every allocation proceeds to the inner allocator unchanged.

Faulty<I, NeverFail> is a transparent passthrough; useful as the “injection disabled” arm of generic code that is parameterised over an AllocFaultPolicy.
