Trait Strategy

pub trait Strategy<T: ?Sized> {
    // Required methods
    fn inject(container: &mut T, context: DatadogContext);
    fn extract(container: &T) -> DatadogContext;
}
Expand description

Strategy for extracting/injecting DatadogContext from/to a container type.

See TraceContextExt for an example of the intended use.

Required Methods§

Source

fn inject(container: &mut T, context: DatadogContext)

Injects a trace context into T.

If the provided context is empty, T is unchanged.

Source

fn extract(container: &T) -> DatadogContext

Extracts a trace context from T.

If T does not contain a valid trace context, the resulting context will be empty.

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.
