Opentelemetry span extension trait. This trait provides helper methods to the tracing::Span for crossing thread and process boundaries.

Required Methods

fn get_context(&self) -> Context

Get the context of this span.

fn get_current_context() -> Context

Get the context of the current span.

fn get_current_bytes() -> Vec<u8>

Get the current span as message pack bytes.

fn set_context(&self, context: Context)

Set the context of this span.

fn set_current_context(context: Context)

Set the context of the current span.

fn set_current_bytes(bytes: Vec<u8>)

Set the current span context from message pack bytes.

fn display_context(&self) -> String

Display this spans context as a String.

Provided Methods

fn get_context_bytes(&self) -> Vec<u8>

Get the context as message pack bytes for sending over process boundaries.

fn set_from_bytes(&self, bytes: Vec<u8>)

Set the context of this span from bytes over the network.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
