Struct AlwaysFail

pub struct AlwaysFail;

Expand description

Policy that fails every allocation.

Faulty<I, AlwaysFail> is an allocator that is permanently out of memory — useful for exercising a caller’s OOM handling in isolation, or as the primary of a WithFallback so that every request is forced onto the fallback path.
