Variants

CapacityOverflow

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

Uncertain how much info should be exposed

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

AllocError

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

Uncertain how much info should be exposed

The memory allocator returned an error
