# Struct crossbeam::mem::epoch::Guard [−] [src]

    #[must_use]
    pub struct Guard {
        // some fields omitted
    }

An RAII-style guard for pinning the current epoch.

A guard must be acquired before most operations on an `Atomic` pointer. On destruction, it unpins the epoch.

## Methods

### `impl Guard`

#### `unsafe fn unlinked<T>(&self, val: Shared<T>)`

Assert that the value is no longer reachable from a lock-free data structure and should be collected when sufficient epochs have passed.

#### `fn migrate_garbage(&self)`

Move the thread-local garbage into the global set of garbage.

## Trait Implementations

### `impl Drop for Guard`

#### `fn drop(&mut self)`

## 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`)
