Struct metrics_observer_json::JsonBuilder

pub struct JsonBuilder { /* fields omitted */ }

Builder for JsonObserver.

Methods

impl JsonBuilder

pub fn new() -> Self

Creates a new JsonBuilder with default values.

pub fn set_quantiles(self, quantiles: &[f64]) -> Self

Sets the quantiles to use when rendering histograms.

Quantiles represent a scale of 0 to 1, where percentiles represent a scale of 1 to 100, so a quantile of 0.99 is the 99th percentile, and a quantile of 0.99 is the 99.9th percentile.

By default, the quantiles will be set to: 0.0, 0.5, 0.9, 0.95, 0.99, 0.999, and 1.0.

pub fn set_pretty_json(self, pretty: bool) -> Self

Sets whether or not to render the JSON as "pretty."

Pretty JSON refers to the formatting and identation, where different fields are on different lines, and depending on their depth from the root object, are indented.

By default, pretty mode is not enabled.
