Struct SampleReady 

pub struct SampleReady {
    pub batch_iter: Option<ClientEnd<BatchIteratorMarker>>,
    pub seconds_since_start: Option<i64>,
    /* private fields */
}

SampleReady carries the data for a ready-to-consume sample.

Fields

batch_iter: Option<ClientEnd<BatchIteratorMarker>>

batch_iter is the BatchIterator over the set of data.

seconds_since_start: Option<i64>

seconds_since_start is ticks * interval_secs for the current polling period.

This can be used to check whether a value in the batch corresponds to a SampleDatum, assuming you have not registered the same selector with different SampleStrategy types. The procedure is:

1. Resolve batch_iter into a set of Inspect hierarchies.
2. Filter the set of SampleDatums committed to this server with the predicate seconds_since_start % datum.interval_secs == 0.
3. Any selector from the filtered SampleDatums that matches data in the resolved Inspect hierarchies is valid.

If you DO have one selector registered twice with different strategies, you must maintain a local cache and check the value yourself.

Trait Implementations

impl Debug for SampleReady

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

Formats the value using the given formatter.

impl Decode<SampleReady, DefaultFuchsiaResourceDialect> for SampleReady

fn new_empty() -> Self

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<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

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

impl Default for SampleReady

fn default() -> SampleReady

Returns the “default value” for a type.

impl Encode<SampleReady, DefaultFuchsiaResourceDialect> for &mut SampleReady

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

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

impl PartialEq for SampleReady

fn eq(&self, other: &SampleReady) -> 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 ResourceTypeMarker for SampleReady

type Borrowed<'a> = &'a mut SampleReady

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

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl TypeMarker for SampleReady

type Owned = SampleReady

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.
