# `Send` and `Sync`
|
||
|
|
|

|
|
How does Rust know to forbid shared access across thread? The answer is in two traits:
|
||
|
|
|
||
|
|
* [`Send`][1]: a type `T` is `Send` if it is safe to move a `T` across a thread
|
||
|
|
boundary.
|
||
|
|
* [`Sync`][2]: a type `T` is `Sync` if it is safe to move a `&T` across a thread
|
||
|
|
boundary.
