Struct QueryRequest 

pub struct QueryRequest {
    pub metric: String,
    pub query: String,
    pub start: Option<Timestamp>,
    pub end: Option<Timestamp>,
    pub step_secs: u64,
}

A metrics query request.

Fields

metric: String

The metric name (e.g., “cpu_usage”, “http_requests_total”).

query: String

The PromQL query string (e.g., “sum(cpu_usage{env="prod"}) by (region)”).

start: Option<Timestamp>

Start of the query time range (nanoseconds since epoch). If None, defaults to backend-specific behavior (e.g., 1 hour ago).

end: Option<Timestamp>

End of the query time range (nanoseconds since epoch). If None, defaults to now.

step_secs: u64

Query step/granularity in seconds. This determines the resolution of the returned data points.
