Struct Pmt 

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

An object representing a Zircon Pinned Memory Token. See PMT Documentation for details.

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

Implementations

impl Pmt

pub fn raw_handle(&self) -> u32

Return the handle’s integer value.

pub fn invalid() -> Pmt

pub fn is_invalid(&self) -> bool

pub fn into_raw(self) -> u32

Return the raw handle’s integer value without closing it when self is dropped.

pub fn unowned(&self) -> Unowned<'_, Pmt>

Returns an [Unowned] referring to this handle.

pub fn as_handle_ref(&self) -> Unowned<'_, NullableHandle>

Returns a [HandleRef] referring to this handle.

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

Wraps the zx_handle_duplicate syscall.

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

Wraps the zx_handle_replace syscall.

pub fn into_handle(self) -> NullableHandle

Converts the value into its inner handle.

pub fn signal( &self, clear_mask: Signals, set_mask: Signals, ) -> Result<(), Status>

Wraps the zx_object_signal syscall.

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

Wraps the zx_object_wait_one syscall.

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

Wraps the zx_object_wait_async syscall.

pub fn wait_item(&self, signals: Signals) -> WaitItem<'_>

Return a WaitItem for this handle and the provided signals to use with object_wait_many.

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

Wraps a call to the zx_object_get_property syscall for the ZX_PROP_NAME property.

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

Wraps a call to the zx_object_set_property syscall for the ZX_PROP_NAME property.

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

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_BASIC topic.

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

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_COUNT topic.

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

Returns the [Koid] for the object referred to by this handle.

impl Pmt

pub unsafe fn unpin(self) -> Result<(), Status>

Unpins a Pinned Memory Token. Wraps the zx_pmt_unpin system call to unpin a pmt.

This function is marked unsafe because calling it at the wrong time (i.e., while hardware is still accessing the pinned memory) can lead to memory corruption.

Safety

The caller must ensure hardware is no longer accessing the memory that has been pinned or else risk arbitrary memory corruption. It is strongly recommended you do not call this in a drop method.

Trait Implementations

impl AsHandleRef for Pmt

fn as_handle_ref(&self) -> Unowned<'_, NullableHandle>

Get a reference to the handle. One important use of such a reference is for object_wait_many.

impl Debug for Pmt

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<Handle> for Pmt

fn from(handle: Handle) -> Pmt

Converts to this type from the input type.

impl From<NullableHandle> for Pmt

fn from(handle: NullableHandle) -> Pmt

Converts to this type from the input type.

impl From<Pmt> for NullableHandle

fn from(x: Pmt) -> NullableHandle

Converts to this type from the input type.

impl Hash for Pmt

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Pmt

fn cmp(&self, other: &Pmt) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Pmt

fn eq(&self, other: &Pmt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Pmt

fn partial_cmp(&self, other: &Pmt) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
