folly::FiberIOExecutor

Synopsis

Declared in <folly/executors/FiberIOExecutor.h>

class FiberIOExecutor
    : public IOExecutor

A FiberIOExecutor wraps an IOExecutor, but executes funcs on the FiberManager mapped to the underlying IOExector's event base.

Name	Description
`IOExecutor`	An executor backed by an I/O event loop.

Name	Description
`KeepAlive`	Alias for ExecutorKeepAlive, a safe pointer to an Executor.

Name	Description
`FiberIOExecutor` [constructor]	Constructs the executor from a backing IO executor.
`add`	`add` overloads
`addWithPriority` [virtual]	Enqueue a function with a given priority, where 0 is the medium priority This is up to the implementation to enforce
`getEventBase` [virtual]	Returns the event base of the backing IO executor.
`getNumPriorities` [virtual]	Returns the number of priority levels this executor supports.

Name	Description
`getKeepAliveToken`	`getKeepAliveToken` overloads
`invokeCatchingExns`	Invokes `f`, logging and swallowing any exception it throws.

Name	Description
`HI_PRI`	Highest schedulable priority.
`LO_PRI`	Lowest schedulable priority.
`MID_PRI`	Medium (default) schedulable priority.

Name	Description
`keepAliveAcquire` [virtual]	Acquire a keep alive token. Should return false if keep-alive mechanism is not supported.
`keepAliveRelease` [virtual]	Release a keep alive token previously acquired by keepAliveAcquire(). Will never be called if keepAliveAcquire() returns false.

Name	Description
`isKeepAliveDummy`	Returns true if the KeepAlive is constructed from an executor that does not support the keep alive ref-counting functionality
`keepAliveAcquire`	Acquires a keep-alive reference on `executor`.
`keepAliveRelease`	Releases a keep-alive reference on `executor`.
`makeKeepAlive`	Makes a counted (non-dummy, non-alias) keep-alive referring to `executor`.

Name	Description
`async_tracing::logFutureVia`	Trace hook invoked when a Future is rescheduled onto an executor.
`async_tracing::logGetGlobalCPUExecutor`	Trace hook invoked when the global CPU executor is retrieved.
`async_tracing::logGetGlobalIOExecutor`	Trace hook invoked when the global IO executor is retrieved.
`async_tracing::logGetImmutableCPUExecutor`	Trace hook invoked when the immutable CPU executor is retrieved.
`async_tracing::logGetImmutableIOExecutor`	Trace hook invoked when the immutable IO executor is retrieved.
`async_tracing::logSemiFutureVia`	Trace hook invoked when a SemiFuture is rescheduled onto an executor.
`async_tracing::logSetGlobalCPUExecutor`	Trace hook invoked when the global CPU executor is set.
`async_tracing::logSetGlobalIOExecutor`	Trace hook invoked when the global IO executor is set.
