Struct Snapshot

pub struct Snapshot {
    pub attributions: Option<Vec<Attribution>>,
    pub principals: Option<Vec<Principal>>,
    pub resources: Option<Vec<Resource>>,
    pub resource_names: Option<Vec<String>>,
    pub kernel_statistics: Option<KernelStatistics>,
    /* private fields */
}

Snapshot of the memory usage of the system, as seen by the server.

Fields

attributions: Option<Vec<Attribution>>

List of attribution claims.

principals: Option<Vec<Principal>>

List of Principals on the system.

resources: Option<Vec<Resource>>

List of kernel memory resources on the system. These resources are attributed to Principals by other Principals.

resource_names: Option<Vec<String>>

Map from the vector index to the name of kernel resources. Resource names are often repeated across many resources; using this indirection reduces the amount of duplication within a Snapshot object.

kernel_statistics: Option<KernelStatistics>

System-wide memory statistics from the kernel.

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Snapshot

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<Snapshot, D> for Snapshot

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

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

impl Default for Snapshot

fn default() -> Snapshot

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<Snapshot, D> for &Snapshot

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, 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 Snapshot

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

type Owned = Snapshot

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 Snapshot

type Borrowed<'a> = &'a Snapshot

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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