Struct prometheus_http_query::TargetMetadataQueryBuilder

pub struct TargetMetadataQueryBuilder<'a> { /* private fields */ }

Provides methods to build a query to the target metadata endpoint and send it to Prometheus.

Implementations

impl<'a> TargetMetadataQueryBuilder<'a>

Note that Prometheus combines all filters that have been set in the final request and only returns target metadata that matches all filters.
See the official documentation for a thorough explanation on the filters that can be set: Prometheus API documentation.

pub fn match_target(self, selector: &'a Selector<'a>) -> Self

Pass a label selector to instruct Prometheus to filter targets by their label sets. Calling this repeatedly will replace the current label selector.

pub fn metric(self, metric: impl Display) -> Self

Set this to only retrieve target metadata for this metric. Calling this repeatedly will replace the current metric name.

pub fn limit(self, limit: i32) -> Self

Limit the maximum number of targets to match. Calling this repeatedly will replace the current limit.

pub async fn get(self) -> Result<Vec<TargetMetadata>, Error>

Execute the target metadata query (using HTTP GET) and return the collection of TargetMetadata sent by Prometheus.

pub async fn get_raw(self) -> Result<Response, Error>

Execute the target metadata query (using HTTP GET) and return the raw response sent by Prometheus.

Trait Implementations

impl<'a> Clone for TargetMetadataQueryBuilder<'a>

fn clone(&self) -> TargetMetadataQueryBuilder<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
