Struct ChromeHistogramSample 

pub struct ChromeHistogramSample {
    pub name_hash: Option<u64>,
    pub name: Option<String>,
    pub sample: Option<i64>,
    pub name_iid: Option<u64>,
}

An individual histogram sample logged via Chrome’s UMA metrics system.

Fields

name_hash: Option<u64>

MD5 hash of the metric name. Either |name_hash| or |name|/|name_iid| or both must be present.

name: Option<String>

sample: Option<i64>

name_iid: Option<u64>

Interned HistogramName. Only one of |name|, |name_iid| can be set.

Implementations

impl ChromeHistogramSample

pub fn name_hash(&self) -> u64

Returns the value of name_hash, or the default value if name_hash is unset.

pub fn name(&self) -> &str

Returns the value of name, or the default value if name is unset.

pub fn sample(&self) -> i64

Returns the value of sample, or the default value if sample is unset.

pub fn name_iid(&self) -> u64

Returns the value of name_iid, or the default value if name_iid is unset.

Trait Implementations

impl Clone for ChromeHistogramSample

fn clone(&self) -> ChromeHistogramSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChromeHistogramSample

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

Formats the value using the given formatter.

impl Default for ChromeHistogramSample

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ChromeHistogramSample

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 Message for ChromeHistogramSample

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ChromeHistogramSample

fn eq(&self, other: &ChromeHistogramSample) -> 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.
