Struct MatrixSelector 

pub struct MatrixSelector {
    pub selector: VectorSelector,
    pub range: Duration,
}

A matrix selector expression (range vector).

Selects a range of samples over time for each matching time series. Extends a vector selector with a duration in square brackets.

Example

use rusty_promql_parser::parser::selector::{MatrixSelector, VectorSelector};
use rusty_promql_parser::lexer::duration::Duration;

let sel = MatrixSelector::with_name("http_requests", Duration::from_secs(300));
assert_eq!(sel.to_string(), "http_requests[5m]");

Fields

selector: VectorSelector

The underlying vector selector.

range: Duration

The range duration (e.g., 5m, 1h, 30s).

Implementations

impl MatrixSelector

pub fn new(selector: VectorSelector, range: Duration) -> Self

Create a new matrix selector from a vector selector and range

pub fn with_name(name: impl Into<String>, range: Duration) -> Self

Create a matrix selector with just a metric name and range

pub fn name(&self) -> Option<&str>

Get the metric name (if any)

pub fn matchers(&self) -> &[LabelMatcher]

Get the label matchers

pub fn range_millis(&self) -> i64

Get the range duration in milliseconds

pub fn offset(&self) -> Option<&Duration>

Get the offset duration (if any)

pub fn offset_millis(&self) -> Option<i64>

Get the offset duration in milliseconds (if any)

pub fn at(&self) -> Option<&AtModifier>

Get the @ modifier (if any)

Trait Implementations

impl Clone for MatrixSelector

fn clone(&self) -> MatrixSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatrixSelector

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

Formats the value using the given formatter.

impl Display for MatrixSelector

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

Formats the value using the given formatter.

impl PartialEq for MatrixSelector

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