Struct ServiceLevelIndicator

#[non_exhaustive]
pub struct ServiceLevelIndicator {
    pub type: Option<Type>,
}

A Service-Level Indicator (SLI) describes the “performance” of a service. For some services, the SLI is well-defined. In such cases, the SLI can be described easily by referencing the well-known SLI and providing the needed parameters. Alternatively, a “custom” SLI can be defined with a query to the underlying metric store. An SLI is defined to be good_service / total_service over any queried time interval. The value of performance always falls into the range 0 <= performance <= 1. A custom SLI describes how to compute this ratio, whether this is by dividing values from a pair of time series, cutting a Distribution into good and bad counts, or counting time windows in which the service complies with a criterion. For separation of concerns, a single Service-Level Indicator measures performance for only one aspect of service quality, such as fraction of successful queries or fast-enough queries.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

type: Option<Type>

Service level indicators can be grouped by whether the “unit” of service being measured is based on counts of good requests or on counts of good time windows

Implementations

impl ServiceLevelIndicator

pub fn set_type<T: Into<Option<Type>>>(self, v: T) -> Self

Sets the value of r#type.

pub fn get_basic_sli(&self) -> Option<&Box<BasicSli>>

The value of [r#type][crate::model::ServiceLevelIndicator::r#type] if it holds a BasicSli, None if the field is not set or holds a different branch.

pub fn get_request_based(&self) -> Option<&Box<RequestBasedSli>>

The value of [r#type][crate::model::ServiceLevelIndicator::r#type] if it holds a RequestBased, None if the field is not set or holds a different branch.

pub fn get_windows_based(&self) -> Option<&Box<WindowsBasedSli>>

The value of [r#type][crate::model::ServiceLevelIndicator::r#type] if it holds a WindowsBased, None if the field is not set or holds a different branch.

pub fn set_basic_sli<T: Into<Box<BasicSli>>>(self, v: T) -> Self

Sets the value of [r#type][crate::model::ServiceLevelIndicator::r#type] to hold a BasicSli.

Note that all the setters affecting r#type are mutually exclusive.

pub fn set_request_based<T: Into<Box<RequestBasedSli>>>(self, v: T) -> Self

Sets the value of [r#type][crate::model::ServiceLevelIndicator::r#type] to hold a RequestBased.

Note that all the setters affecting r#type are mutually exclusive.

pub fn set_windows_based<T: Into<Box<WindowsBasedSli>>>(self, v: T) -> Self

Sets the value of [r#type][crate::model::ServiceLevelIndicator::r#type] to hold a WindowsBased.

Note that all the setters affecting r#type are mutually exclusive.

Trait Implementations

impl Clone for ServiceLevelIndicator

fn clone(&self) -> ServiceLevelIndicator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceLevelIndicator

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

Formats the value using the given formatter.

impl Default for ServiceLevelIndicator

fn default() -> ServiceLevelIndicator

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ServiceLevelIndicator

where ServiceLevelIndicator: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for ServiceLevelIndicator

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ServiceLevelIndicator

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
