Enum opentelemetry::Value

source ·
#[non_exhaustive]
pub enum Value { Bool(bool), I64(i64), F64(f64), String(StringValue), Array(Array), }
Expand description

The value part of attribute KeyValue pairs.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Bool(bool)

bool values

§

I64(i64)

i64 values

§

F64(f64)

f64 values

§

String(StringValue)

String values

§

Array(Array)

Array of homogeneous values
