Enum opentelemetry::trace::TraceStateError

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

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.

Trait Implementations

impl Debug for TraceStateError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TraceStateError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TraceStateError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide(&'a self, demand: &mut Demand<'a>)
