Enum opentelemetry::trace::TraceStateError

#[non_exhaustive]
pub enum TraceStateError {
    InvalidKey(String),
    InvalidValue(String),
    InvalidList(String),
}

This is supported on crate feature trace only.

Error returned by TraceState operations.

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.

InvalidKey(String)

The key is invalid. See https://www.w3.org/TR/trace-context/#key for requirement for keys.

InvalidValue(String)

The value is invalid. See https://www.w3.org/TR/trace-context/#value for requirement for values.

InvalidList(String)

The value is invalid. See https://www.w3.org/TR/trace-context/#list for requirement for list members.
