Enum AttributionUpdate

pub enum AttributionUpdate {
    Add(NewPrincipal),
    Update(UpdatedPrincipal),
    Remove(u64),
    // some variants omitted
}

Describes a change affecting attribution of resources to a single principal.

Variants

Add(NewPrincipal)

Reports a new principal managed by the reporter.

Declaring a Principal means that the declarer/reporter is providing the resources for the Principal to run. Typically, Component Framework Runners will declare the components they run as Principals.

Update(UpdatedPrincipal)

Replaces the attribution information for a Principal.

When this is received, the client is should discard any attribution information received by this channel for the Principal, and replace it with this information.

Remove(u64)

Removes a Principal.

Declares that a Principal is no longer active on the system. All attribution information for this Principal can be removed after this message. Any remaining resources will still be attributed according to the default attribution rules.

Implementations

impl AttributionUpdate

pub fn ordinal(&self) -> u64

pub fn unknown_variant_for_testing() -> Self

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Debug for AttributionUpdate

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

Formats the value using the given formatter.

impl Decode<AttributionUpdate, DefaultFuchsiaResourceDialect> for AttributionUpdate

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 Encode<AttributionUpdate, DefaultFuchsiaResourceDialect> for &mut AttributionUpdate

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 AttributionUpdate

fn eq(&self, other: &Self) -> 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 AttributionUpdate

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

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 AttributionUpdate

type Owned = AttributionUpdate

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.
