Enum alloc_wg::collections::CollectionAllocErr

pub enum CollectionAllocErr<B: BuildAllocRef> where
    B::Ref: AllocRef,  {
    CapacityOverflow,
    AllocError {
        layout: NonZeroLayout,
        inner: <B::Ref as AllocRef>::Error,
    },
}

Augments AllocErr with a CapacityOverflow variant.

Variants

CapacityOverflow

Error due to the computed capacity exceeding the collection's maximum (usually isize::MAX bytes).

AllocError

The memory allocator returned an error

Fields of AllocError

layout: NonZeroLayout

The layout of allocation request that failed

inner: <B::Ref as AllocRef>::Error

Error returned by the allocator

Trait Implementations
