Enum prometheus_http_query::response::Data

pub enum Data {
    Vector(Vec<InstantVector>),
    Matrix(Vec<RangeVector>),
    Scalar(Sample),
}

A wrapper for possible result types of expression queries (crate::Client::query and crate::Client::query_range).

Variants

Vector(Vec<InstantVector>)

Matrix(Vec<RangeVector>)

Scalar(Sample)

Implementations

impl Data

pub fn as_vector(&self) -> Option<&[InstantVector]>

If the result type of the query is vector, returns an array of InstantVectors. Returns None otherwise.

pub fn as_matrix(&self) -> Option<&[RangeVector]>

If the result type of the query is matrix returns an array of RangeVectors. Returns None otherwise.

pub fn as_scalar(&self) -> Option<&Sample>

If the result type of the query is scalar, returns a single Sample. Returns None otherwise.

pub fn is_vector(&self) -> bool

Check if this PromqlResult contains a list of InstantVectors (i.e. result type vector).

pub fn is_matrix(&self) -> bool

Check if this PromqlResult contains a list of RangeVectors (i.e. result type matrix).

pub fn is_scalar(&self) -> bool

Check if this PromqlResult contains a scalar value (i.e. result type scalar, a single Sample).

pub fn is_empty(&self) -> bool

This is a shortcut to check if the query returned any data at all regardless of the exact type.

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Data

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

Formats the value using the given formatter.
