Struct TraceOptions 

pub struct TraceOptions {
    pub duration_ns: Option<i64>,
    pub triggers: Option<Vec<Trigger>>,
    pub requested_categories: Option<Vec<String>>,
    /* private fields */
}

Covers how a trace will be run when invoking StartRecording.

Fields

duration_ns: Option<i64>

Determines how long a trace recording will run before terminating in nanoseconds. This is an “at-least” duration, with the actual runtime terminating likely a few dozen milliseconds longer.

If this is not set, a trace will run indefinitely and must be stopped using StopRecording. Or by cleanly shutting down the daemon via ffx daemon stop or by using the Deamon proxy itself.

triggers: Option<Vec<Trigger>>

The triggers to run against this trace.

requested_categories: Option<Vec<String>>

The requested categories for the trace. These could include groups, or nothing. These categories are expanded and the expanded list is in the TraceConfig. This list is used to support the nice UX of explicitly checking for events with these categories and warn the user if the no events were captured for any of these categories.

Trait Implementations

impl Clone for TraceOptions

fn clone(&self) -> TraceOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceOptions

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

Formats the value using the given formatter.

impl<D> Decode<TraceOptions, D> for TraceOptions

where D: ResourceDialect,

fn new_empty() -> TraceOptions

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 Default for TraceOptions

fn default() -> TraceOptions

Returns the “default value” for a type.

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

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 TraceOptions

fn eq(&self, other: &TraceOptions) -> 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 TraceOptions

type Owned = TraceOptions

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 TraceOptions

type Borrowed<'a> = &'a TraceOptions

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: &<TraceOptions as TypeMarker>::Owned, ) -> <TraceOptions as ValueTypeMarker>::Borrowed<'_>

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