# Enum std::alloc::CollectionAllocErr[−][src]

    pub enum CollectionAllocErr {
        CapacityOverflow,
        AllocErr,
    }

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

new API

Augments `AllocErr` with a CapacityOverflow variant.

## Variants

`CapacityOverflow`
🔬 This is a nightly-only experimental API. (`try_reserve` #48043)

new API

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

`AllocErr`
🔬 This is a nightly-only experimental API. (`try_reserve` #48043)

new API

Error due to the allocator (see the `AllocErr` type's docs).

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
