String representation of the node that returns the given node when parsed as part of a valid query.

func (*Builder) Type ¶

func (b *Builder) Type() parser.ValueType

Type returns the type the expression evaluates to. It does not perform in-depth checks as this is done at parsing-time.

type Option ¶

func WithRange ¶

func WithRange(d time.Duration) Option

func WithRangeAsString ¶

func WithRangeAsString(d string) Option

WithRangeAsString sets the range as a string like "3h2m1s".

func WithRangeAsVariable ¶

func WithRangeAsVariable(name string) Option

WithRangeAsVariable sets the range as a variable name. It will be useful in case you are writing a query for a dashboard and the range is a variable like "$__rate_interval". Use it if your range is not correct in terms of PromQL syntax.
