Trait FutureExt

pub trait FutureExt: Sized {
    // Provided methods
    fn with_context(self, otel_cx: Context) -> WithContext<Self>  { ... }
    fn with_current_context(self) -> WithContext<Self>  { ... }
}

Available on crate feature trace only.

Extension trait allowing futures, streams, and sinks to be traced with a span.

Provided Methods

fn with_context(self, otel_cx: Context) -> WithContext<Self>

Attaches the provided Context to this type, returning a WithContext wrapper.

When the wrapped type is a future, stream, or sink, the attached context will be set as current while it is being polled.

fn with_current_context(self) -> WithContext<Self>

Attaches the current Context to this type, returning a WithContext wrapper.

When the wrapped type is a future, stream, or sink, the attached context will be set as the default while it is being polled.

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.
