Struct promql_parser::parser::ast::SubqueryExpr

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

Grammar:

<instant_query> '[' <range> ':' [<resolution>] ']' [ @ <float_literal> ] [ offset <duration> ]

Fields

expr: Box<Expr>

offset: Option<Offset>

at: Option<AtModifier>

range: Duration

step: Option<Duration>

Default is the global evaluation interval.

Trait Implementations

impl Clone for SubqueryExpr

fn clone(&self) -> SubqueryExpr

Returns a copy 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<SubqueryExpr> for SubqueryExpr

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Prettier for SubqueryExpr

fn pretty(&self, level: usize, max: usize) -> String

max param is short for max_characters_per_line.

fn format(&self, level: usize, _max: usize) -> String

override format if expr needs to be splited into multiple lines

fn needs_split(&self, max: usize) -> bool

override needs_split to return false, in order not to split multiple lines
