Expand description
This module defines types which are thread safe if cfg!(feature = "concurrent") 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 reference 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§
- Lazy
- A value which is initialized on the first access.
- Lock
- Lock
Cell - Lock
Guard - A wrapper type for a mutably borrowed value from a
RefCell<T>. - Lrc
- A single-threaded reference-counting pointer. ‘Rc’ stands for ‘Reference Counted’.
- Mapped
Lock Guard - A wrapper type for a mutably borrowed value from a
RefCell<T>. - Mapped
Write Guard - A wrapper type for a mutably borrowed value from a
RefCell<T>. - Once
Cell - A cell which can be written to only once. It is not thread safe.
- Read
Guard - Wraps a borrowed reference to a value in a
RefCellbox. A wrapper type for an immutably borrowed value from aRefCell<T>. - RwLock
- Weak
Weakis a version ofRcthat holds a non-owning reference to the managed allocation.- Write
Guard - A wrapper type for a mutably borrowed value from a
RefCell<T>.
Traits§
- Hash
MapExt - Send
- Dummy trait because swc_common is in single thread mode.
- Sync
- Dummy trait because swc_common is in single thread mode.
