# 1.12.0[−][src]Struct alloc::collections::binary_heap::PeekMut

    pub struct PeekMut<'a, T: 'a + Ord> { /* fields omitted */ }

Structure wrapping a mutable reference to the greatest item on a `BinaryHeap`.

This `struct` is created by the `peek_mut` method on `BinaryHeap`. See its documentation for more.

## 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`)
