Struct MemoryStatistics

pub struct MemoryStatistics {
    pub time: Option<Time>,
    pub kernel_statistics: Option<KernelStatistics>,
    pub performance_metrics: Option<PerformanceImpactMetrics>,
    /* private fields */
}

System-level memory statistics of a device, as seen by the server. This table does not contain any process, component or principal-level information, and is faster to compute than a memory snapshot.

Fields

time: Option<Time>

Time of the device when this data was collected.

kernel_statistics: Option<KernelStatistics>

System-wide memory statistics from the kernel.

performance_metrics: Option<PerformanceImpactMetrics>

Details of performance impact of memory usage (e.g. thrashing, stalling, etc)

Trait Implementations

impl Clone for MemoryStatistics

fn clone(&self) -> MemoryStatistics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryStatistics

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

Formats the value using the given formatter.

impl<D> Decode<MemoryStatistics, D> for MemoryStatistics

where D: ResourceDialect,

fn new_empty() -> MemoryStatistics

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 MemoryStatistics

fn default() -> MemoryStatistics

Returns the “default value” for a type.

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

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 MemoryStatistics

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

type Owned = MemoryStatistics

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 MemoryStatistics

type Borrowed<'a> = &'a MemoryStatistics

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

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