Module rustc_data_structures::sync[−][src]

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

This module defines types which are thread safe if cfg!(parallel_queries) is true.

Lrc is an alias of either Rc or Arc.

Lock is a mutex. It internally uses parking_lot::Mutex if cfg!(parallel_queries) is true, RefCell otherwise.

RwLock is a read-write lock. It internally uses parking_lot::RwLock if cfg!(parallel_queries) is true, RefCell otherwise.

LockCell is a thread safe version of Cell, with set and get operations. It can never deadlock. It uses Cell when cfg!(parallel_queries) is false, otherwise it is a Lock.

MTLock is a mutex which disappears if cfg!(parallel_queries) is false.

MTRef is a immutable refernce if cfg!(parallel_queries), and an mutable reference otherwise.

rustc_erase_owner! erases a OwningRef owner into Erased or Erased + Send + Sync depending on the value of cfg!(parallel_queries).

Structs

LockGuard	A wrapper type for a mutably borrowed value from a `RefCell<T>`.
Lrc	A single-threaded reference-counting pointer. 'Rc' stands for 'Reference Counted'.
ReadGuard	Wraps a borrowed reference to a value in a `RefCell` box. A wrapper type for an immutably borrowed value from a `RefCell<T>`.
Weak	`Weak` is a version of `Rc` that holds a non-owning reference to the managed value. The value is accessed by calling `upgrade` on the `Weak` pointer, which returns an `Option<Rc<T>>`.
WriteGuard	A wrapper type for a mutably borrowed value from a `RefCell<T>`.

LockCell	[ Experimental ]
MTLock	[ Experimental ]
Once	[ Experimental ] A type whose inner value can be written once and then will stay read-only
OneThread	[ Experimental ] A type which only allows its inner value to be used in one thread. It will panic if it is used on multiple threads.
