[−][src]Struct std::alloc::AllocErr

pub struct AllocErr;

🔬 This is a nightly-only experimental API. (allocator_api #32838)

The AllocErr error indicates an allocation failure that may be due to resource exhaustion or to something wrong when combining the given input arguments with this allocator.
