Struct Thread 

pub struct Thread(/* private fields */);

An object representing a Zircon thread.

As essentially a subtype of Handle, it can be freely interconverted.

Implementations

impl Thread

pub fn start( &self, thread_entry: usize, stack: usize, arg1: usize, arg2: usize, ) -> Result<(), Status>

Cause the thread to begin execution.

Wraps the zx_thread_start syscall.

pub fn set_profile(&self, profile: Profile, options: u32) -> Result<(), Status>

Apply a scheduling profile to a thread.

Wraps the zx_object_set_profile syscall.

pub unsafe fn exit()

Terminate the current running thread.

Safety

Extreme caution should be used– this is basically always UB in Rust. There’s almost no “normal” program code where this is okay to call. Users should take care that no references could possibly exist to stack variables on this thread, and that any destructors, closure suffixes, or other “after this thing runs” code is waiting to run in order for safety.

pub fn get_exception_report(&self) -> Result<ExceptionReport, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_THREAD_EXCEPTION_REPORT topic.

pub fn get_thread_info(&self) -> Result<ThreadInfo, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_THREAD topic.

pub fn get_stats(&self) -> Result<ThreadStats, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_THREAD_STATS topic.

pub fn write_state_general_regs( &self, state: zx_thread_state_general_regs_t, ) -> Result<(), Status>

pub fn raise_user_exception( options: RaiseExceptionOptions, synth_code: u32, synth_data: u32, ) -> Result<(), Status>

Wraps the zx_thread_raise_exception syscall.

Trait Implementations

impl AsHandleRef for Thread

fn raw_handle(&self) -> u32

Interpret the reference as a raw handle (an integer type). Two distinct handles will have different raw values (so it can perhaps be used as a key in a data structure).

fn wait_handle( &self, signals: Signals, deadline: Instant<MonotonicTimeline>, ) -> WaitResult

Waits on a handle. Wraps the zx_object_wait_one syscall.

fn wait_async_handle( &self, port: &Port, key: u64, signals: Signals, options: WaitAsyncOpts, ) -> Result<(), Status>

Causes packet delivery on the given port when the object changes state and matches signals. zx_object_wait_async syscall.

fn get_name(&self) -> Result<Name, Status>

Get the Property::NAME property for this object.

fn set_name(&self, name: &Name) -> Result<(), Status>

Set the Property::NAME property for this object.

fn basic_info(&self) -> Result<HandleBasicInfo, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_BASIC topic.

fn count_info(&self) -> Result<HandleCountInfo, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_COUNT topic.

fn get_koid(&self) -> Result<Koid, Status>

Returns the koid (kernel object ID) for this handle.

impl HandleBased for Thread

fn duplicate_handle(&self, rights: Rights) -> Result<Self, Status>

Duplicate a handle, possibly reducing the rights available. Wraps the zx_handle_duplicate syscall.

fn replace_handle(self, rights: Rights) -> Result<Self, Status>

Create a replacement for a handle, possibly reducing the rights available. This invalidates the original handle. Wraps the zx_handle_replace syscall.
