Enum opentelemetry::logs::AnyValue

#[non_exhaustive]
pub enum AnyValue {
    Int(i64),
    Double(f64),
    String(StringValue),
    Boolean(bool),
    Bytes(Box<Vec<u8>>),
    ListAny(Box<Vec<AnyValue>>),
    Map(Box<HashMap<Key, AnyValue>>),
}

Value types for representing arbitrary values in a log record. Note: The tracing and log crates only support basic types that can be converted to these core variants: i64, f64, StringValue, and bool. Any complex and custom types are supported through their Debug implementation, and converted to String. More complex types (Bytes, ListAny, and Map) are included here to meet specification requirements and are available to support custom appenders that may be implemented for other logging crates. These types allow for handling dynamic data structures, so keep in mind the potential performance overhead of using boxed vectors and maps in appenders.

Variants (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.

Int(i64)

An integer value

Double(f64)

A double value

String(StringValue)

A string value

Boolean(bool)

A boolean value

Bytes(Box<Vec<u8>>)

A byte array

ListAny(Box<Vec<AnyValue>>)

An array of Any values

Map(Box<HashMap<Key, AnyValue>>)

A map of string keys to Any values, arbitrarily nested.

impl<K: Into<Key>, V: Into<AnyValue>> FromIterator<(K, V)> for AnyValue

fn from_iter<I: IntoIterator<Item = (K, V)>>(iter: I) -> Self

Creates an AnyValue::Map value from a sequence of key-value pairs that can be converted into a Key and AnyValue respectively.
