# Struct alloc::boxed::ExchangeHeapSingleton [−] [src]

    pub struct ExchangeHeapSingleton { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (`box_heap` #27779)

may be renamed; uncertain about custom allocator design

This the singleton type used solely for `boxed::HEAP`.

## 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`)
