State data storage for @c start_table_io_wait_v1_t, @c start_table_lock_wait_v1_t. This structure provide temporary storage to a table locker. The content of this structure is considered opaque, the fields are only hints of what an implementation of the psi interface can use. This memory is provided by the instrumented code for performance reasons. @sa start_table_io_wait_v1_t @sa start_table_lock_wait_v1_t

Fields

m_flags: uint

Internal state.

m_io_operation: Type

Current io operation.

m_table: *mut PSI_table

Current table handle.

m_table_share: *mut PSI_table_share

Current table share.

m_thread: *mut PSI_thread

Current thread.

m_timer_start: ulonglong

Timer start.

m_timer: Option<unsafe extern "C" fn() -> ulonglong>

Timer function.

m_wait: *mut c_void

Internal data.

m_index: uint

Implementation specific. For table io, the table io index. For table lock, the lock type.
