Detailed Description

Runtime options.

Options for configuring the behavior of a Runtime instance. Most of them are io_uring setup options. These options should be set before creating the Runtime instance.

Definition at line 23 of file runtime_options.hpp.

Member Function Documentation

cq_size()

Self & condy::RuntimeOptions::cq_size ( size_t v )

inline

Set CQ size.

Parameters

v

CQ size

Definition at line 129 of file runtime_options.hpp.

disable_register_ring_fd()

Self & condy::RuntimeOptions::disable_register_ring_fd ( )

inline

Disable register ring fd.

By default, the runtime registers the ring file descriptor with the kernel for performance optimization. This option disables that behavior.

Deprecated

This option is deprecated and will be removed in future versions.

Definition at line 48 of file runtime_options.hpp.

enable_attach_wq()

Self & condy::RuntimeOptions::enable_attach_wq ( Runtime & other )

inline

See IORING_SETUP_ATTACH_WQ.

This option allows the current runtime to share the async worker thread backend with another runtime.

Parameters

other

The other runtime to attach to.

Definition at line 148 of file runtime_options.hpp.

enable_coop_taskrun()

Self & condy::RuntimeOptions::enable_coop_taskrun ( )

inline

See IORING_SETUP_COOP_TASKRUN and IORING_SETUP_TASKRUN_FLAG.

Returns

Self&

Definition at line 157 of file runtime_options.hpp.

enable_defer_taskrun()

Self & condy::RuntimeOptions::enable_defer_taskrun ( )

inline

See IORING_SETUP_DEFER_TASKRUN and IORING_SETUP_TASKRUN_FLAG.

Returns

Self&

Definition at line 103 of file runtime_options.hpp.

enable_sqpoll()

Self & condy::RuntimeOptions::enable_sqpoll ( size_t idle_time_ms = 1000, std::optional< uint32_t > cpu = std::nullopt )

inline

See IORING_SETUP_SQPOLL.

Parameters

idle_time_ms	Idle time in milliseconds for the sqpoll thread
cpu	CPU affinity for the sqpoll thread

Definition at line 80 of file runtime_options.hpp.

event_interval()

Self & condy::RuntimeOptions::event_interval ( size_t v )

inline

Set event interval.

The event interval determines how often the runtime checks for completed events.

Parameters

v	The event interval value

Definition at line 33 of file runtime_options.hpp.

sq_size()

Self & condy::RuntimeOptions::sq_size ( size_t v )

inline

Set SQ size.

Parameters

v

SQ size

Definition at line 120 of file runtime_options.hpp.
