|
|
This crate provides epoch-based garbage collection for building concurrent data structures.
|
|
|
|
When a thread removes an object from a concurrent data structure, other threads
|
|
may be still using pointers to it at the same time, so it cannot be destroyed
|
|
immediately. Epoch-based GC is an efficient mechanism for deferring destruction of
|
|
shared objects until no pointers to them can exist.
|
|
|
|
Everything in this crate except the global GC can be used in `no_std` environments, provided that
|
|
`alloc` feature is enabled.
|
|
|
|
## Usage
|
|
|
|
Add this to your `Cargo.toml`:
|
|
|
|
```toml
|
|
[dependencies]
|
|
crossbeam-epoch = "0.9"
|
|
```
|
|
|
|
## Compatibility
|
|
|
|
Crossbeam Epoch supports stable Rust releases going back at least six months,
|
|
and every time the minimum supported Rust version is increased, a new minor
|
|
version is released. Currently, the minimum supported Rust version is 1.36.
