Struct SubqueryExpr 

pub struct SubqueryExpr {
    pub expr: Expr,
    pub range: Duration,
    pub step: Option<Duration>,
    pub offset: Option<Duration>,
    pub at: Option<AtModifier>,
}

Subquery expression

Fields

expr: Expr

The inner expression to evaluate as a subquery

range: Duration

The time range of the subquery

step: Option<Duration>

Optional step/resolution (if None, uses default evaluation interval)

offset: Option<Duration>

Offset modifier

at: Option<AtModifier>

@ modifier for timestamp pinning

Implementations

impl SubqueryExpr

pub fn new(expr: Expr, range: Duration) -> Self

Create a new subquery expression

pub fn with_step(expr: Expr, range: Duration, step: Duration) -> Self

Create a new subquery expression with step

Trait Implementations

impl Clone for SubqueryExpr

fn clone(&self) -> SubqueryExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubqueryExpr

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

Formats the value using the given formatter.

impl Display for SubqueryExpr

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

Formats the value using the given formatter.

impl PartialEq for SubqueryExpr

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