Struct EventStreamRouteMetadata

pub struct EventStreamRouteMetadata {
    pub scope_moniker: Option<String>,
    pub scope: Option<Vec<Ref>>,
    /* private fields */
}

This value is used internally by event stream routers, to carry information pertinent to the route.

Fields

scope_moniker: Option<String>

The moniker of the component that has set a scope on this event stream. Unset if there is no scope on the event stream.

scope: Option<Vec<Ref>>

The scope(s) from which the consumer of this event stream will be able to observe events. Relative to the scope_moniker. Unset if there is no scope on the event stream.

Trait Implementations

impl Clone for EventStreamRouteMetadata

fn clone(&self) -> EventStreamRouteMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventStreamRouteMetadata

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

Formats the value using the given formatter.

impl<D> Decode<EventStreamRouteMetadata, D> for EventStreamRouteMetadata

where D: ResourceDialect,

fn new_empty() -> EventStreamRouteMetadata

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 EventStreamRouteMetadata

fn default() -> EventStreamRouteMetadata

Returns the “default value” for a type.

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

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 EventStreamRouteMetadata

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

type Owned = EventStreamRouteMetadata

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 EventStreamRouteMetadata

type Borrowed<'a> = &'a EventStreamRouteMetadata

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

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