Module `core.atomic`

The atomic module provides basic support for lock-free concurrent programming.

Functions

Name	Description
`atomicExchange(here, exchangeWith)`	Exchange `exchangeWith` with the memory referenced by `here`. This operation is both lock-free and atomic.
`atomicExchange(here, exchangeWith)`	Exchange `exchangeWith` with the memory referenced by `here`. This operation is both lock-free and atomic.
`atomicFence()`	Inserts a full load/store memory fence (on platforms that need it). This ensures that all loads and stores before a call to this function are executed before any loads and stores after the call.
`atomicFence()`	Inserts a full load/store memory fence (on platforms that need it). This ensures that all loads and stores before a call to this function are executed before any loads and stores after the call.
`atomicLoad(val)`	Loads 'val' from memory and returns it. The memory barrier specified by 'ms' is applied to the operation, which is fully sequenced by default. Valid memory orders are MemoryOrder.raw, MemoryOrder.acq, and MemoryOrder.seq.
`atomicLoad(val)`	Loads 'val' from memory and returns it. The memory barrier specified by 'ms' is applied to the operation, which is fully sequenced by default. Valid memory orders are MemoryOrder.raw, MemoryOrder.acq, and MemoryOrder.seq.
`atomicOp(val, mod)`	Performs the binary operation 'op' on val using 'mod' as the modifier.
`atomicOp(val, mod)`	Performs the binary operation 'op' on val using 'mod' as the modifier.
`atomicStore(val, newval)`	Writes 'newval' into 'val'. The memory barrier specified by 'ms' is applied to the operation, which is fully sequenced by default. Valid memory orders are MemoryOrder.raw, MemoryOrder.rel, and MemoryOrder.seq.
`atomicStore(val, newval)`	Writes 'newval' into 'val'. The memory barrier specified by 'ms' is applied to the operation, which is fully sequenced by default. Valid memory orders are MemoryOrder.raw, MemoryOrder.rel, and MemoryOrder.seq.
`cas(here, ifThis, writeThis)`	Stores 'writeThis' to the memory referenced by 'here' if the value referenced by 'here' is equal to 'ifThis'. This operation is both lock-free and atomic.
`cas(here, ifThis, writeThis)`	Stores 'writeThis' to the memory referenced by 'here' if the value referenced by 'here' is equal to the value referenced by 'ifThis'. The prior value referenced by 'here' is written to `ifThis` and returned to the user. This operation is both lock-free and atomic.
`cas(here, ifThis, writeThis)`	Stores 'writeThis' to the memory referenced by 'here' if the value referenced by 'here' is equal to 'ifThis'. This operation is both lock-free and atomic.
`cas(here, ifThis, writeThis)`	Stores 'writeThis' to the memory referenced by 'here' if the value referenced by 'here' is equal to the value referenced by 'ifThis'. The prior value referenced by 'here' is written to `ifThis` and returned to the user. This operation is both lock-free and atomic.
`testCAS(val)`
`testLoadStore(val)`
`testType(val)`
`testXCHG(val)`
