Implementations

impl Cardinality

pub const Unspecified: Cardinality = Self::CARDINALITY_UNSPECIFIED

Short-name alias for CARDINALITY_UNSPECIFIED.

pub const Low: Cardinality = Self::LOW

Short-name alias for LOW.

pub const Medium: Cardinality = Self::MEDIUM

Short-name alias for MEDIUM.

pub const High: Cardinality = Self::HIGH

Short-name alias for HIGH.

pub const Unbounded: Cardinality = Self::UNBOUNDED

Short-name alias for UNBOUNDED.

pub const fn as_str(self) -> &'static str

pub const fn cap(self) -> u64

Numeric cap: the maximum distinct value count permitted at this level. Returns u64::MAX for Unbounded.

pub const fn is_label_compatible(self) -> bool

pub const fn is_measurement_compatible(self) -> bool

True if this cardinality is permitted on a FieldKind::Measurement field.

Trait Implementations

impl Clone for Cardinality

fn clone(&self) -> Cardinality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cardinality

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

Formats the value using the given formatter.

impl Default for Cardinality

fn default() -> Cardinality

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Cardinality

fn deserialize<D>(d: D) -> Result<Cardinality, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Enumeration for Cardinality

fn from_i32(value: i32) -> Option<Cardinality>

Convert from an i32 wire value to the enum.

fn to_i32(&self) -> i32

Convert the enum to its i32 wire value.

fn proto_name(&self) -> &'static str

The name of this enum variant as it appears in the .proto file.

fn from_proto_name(name: &str) -> Option<Cardinality>

Look up a variant by its protobuf name string.

fn values() -> &'static [Cardinality]

All known variants of this enum, in proto declaration order.

impl FromStr for Cardinality

type Err = UnknownVariant

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Cardinality, <Cardinality as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Cardinality

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

where __H: Hasher,

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 Cardinality

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Cardinality

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Cardinality

fn serialize<S>( &self, s: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,
