Enum Task

pub enum Task {
    Process(u64),
    Thread(u64),
    Job(u64),
    SystemWide(SystemWide),
    // some variants omitted
}

An adhoc set of running tasks to attach to.

Variants

Process(u64)

Profile a process and all threads associated with it.

Thread(u64)

Profile a single thread.

Job(u64)

Profile a job and all processes and threads associated with it.

SystemWide(SystemWide)

Profile everything running on the system.

Equivalent to finding root job’s koid and passing it as a Task::job.

Implementations

impl Task

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> Task

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Task

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

Formats the value using the given formatter.

impl<D> Decode<Task, D> for Task

where D: ResourceDialect,

fn new_empty() -> Task

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl<D> Encode<Task, D> for &Task

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for Task

fn eq(&self, other: &Task) -> 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 TypeMarker for Task

type Owned = Task

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for Task

type Borrowed<'a> = &'a Task

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<Task as TypeMarker>::Owned, ) -> <Task as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
