Enum fidl_fuchsia_metricslogger_test::MetricsLoggerError

#[repr(u32)]
pub enum MetricsLoggerError {
    NoDrivers,
    InvalidSamplingInterval,
    AlreadyLogging,
    DuplicatedMetric,
    TooManyActiveClients,
    InvalidStatisticsInterval,
    Internal,
}

Errors associated with MetricsLogger methods. If the request contains any of the following errors, it will fail without affecting the existing logging tasks.

Variants

NoDrivers

Indicates that no driver is found for requested metric logging.

InvalidSamplingInterval

Indicates that an invalid sampling interval was provided.

AlreadyLogging

Requests to start logging will fail if logging is already active for a given client.

DuplicatedMetric

Indicates that the logging request contains duplicated metric type.

TooManyActiveClients

Indicates that the total number of active clients has reached the allowed maxium (defined by MAX_CONCURRENT_CLIENTS = 20 in the MetricsLogger to keep memory use bounded).

InvalidStatisticsInterval

Indicates that statistics is enabled and an invalid statistics interval is provided.

Internal

Indicates that the request failed due to an internal error.

Implementations

impl MetricsLoggerError

pub fn from_primitive(prim: u32) -> Option<Self>

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict enums should not use is_unknown

Trait Implementations

impl Clone for MetricsLoggerError

fn clone(&self) -> MetricsLoggerError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetricsLoggerError

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

Formats the value using the given formatter.

impl Decode<MetricsLoggerError> for MetricsLoggerError

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

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

impl Encode<MetricsLoggerError> for MetricsLoggerError

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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 Hash for MetricsLoggerError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MetricsLoggerError

fn cmp(&self, other: &MetricsLoggerError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<MetricsLoggerError> for MetricsLoggerError

fn eq(&self, other: &MetricsLoggerError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<MetricsLoggerError> for MetricsLoggerError

fn partial_cmp(&self, other: &MetricsLoggerError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for MetricsLoggerError

type Owned = MetricsLoggerError

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 MetricsLoggerError

type Borrowed<'a> = <MetricsLoggerError as TypeMarker>::Owned

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<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

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