Struct SeriesKey 

pub struct SeriesKey {
    pub metric: String,
    pub tags: Vec<(String, String)>,
}

The canonical key for a series — used for collision detection in the series catalog. Two SeriesKeys that hash to the same SeriesId are a collision; the catalog rehashes with a salt.

Fields

metric: String

tags: Vec<(String, String)>

Implementations

impl SeriesKey

pub fn new(metric: impl Into<String>, tags: Vec<(String, String)>) -> Self

pub fn to_series_id(&self, salt: u64) -> SeriesId

Compute the SeriesId for this key with an optional collision salt.

Trait Implementations

impl Clone for SeriesKey

fn clone(&self) -> SeriesKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SeriesKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SeriesKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SeriesKey

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 PartialEq for SeriesKey

fn eq(&self, other: &SeriesKey) -> 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 Serialize for SeriesKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
