Enum opentelemetry::trace::Status

source ·
pub enum Status {
    Unset,
    Error {
        description: Cow<'static, str>,
    },
    Ok,
}
Expand description

The status of a Span.

These values form a total order: Ok > Error > Unset. This means that setting Status::Ok will override any prior or future attempts to set a status with Status::Error or Status::Unset.

The status should remain unset, except for the following circumstances:

Generally, instrumentation libraries should not set the code to Status::Ok, unless explicitly configured to do so. Instrumentation libraries should leave the status code as unset unless there is an error.

Application developers and operators may set the status code to Status::Ok.

When span status is set to Status::Ok it should be considered final and any further attempts to change it should be ignored.

Analysis tools should respond to a Status::Ok status by suppressing any errors they would otherwise generate. For example, to suppress noisy errors such as 404s.

Only the value of the last call will be recorded, and implementations are free to ignore previous calls.

Variants§

§

Unset

The default status.

§

Error

The operation contains an error.

Fields

§description: Cow<'static, str>

The description of the error

§

Ok

The operation has been validated by an application developer or operator to have completed successfully.

Implementations§

source§

impl Status

source

pub fn error(description: impl Into<Cow<'static, str>>) -> Self

Create a new error status with a given description.

§Examples
use opentelemetry::trace::Status;

// record error with `str` description
let error_status = Status::error("something went wrong");

// or with `String` description
let error_status = Status::error(format!("too many foos: {}", 42));
