Details of the allocation that caused a TryReserveError

Variants

`CapacityOverflow`

🔬 This is a nightly-only experimental API. (try_reserve_kind #48043)

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

`AllocError`

Fields

layout: Layout

🔬 This is a nightly-only experimental API. (try_reserve_kind #48043)

The layout of allocation request that failed

🔬 This is a nightly-only experimental API. (try_reserve_kind #48043)
