Trait Observe

pub trait Observe: Sized {
    // Required method
    fn observe(self, name: &str) -> Instrumented<Self>;
}

Instruments a future with a tracing span.

This span is given the trace_tools::observe target, so that it can be more easily filtered in any subscribers or subscriber layers. It also records the future’s calling location in its fields.

Required Methods

fn observe(self, name: &str) -> Instrumented<Self>

Instruments Self with a tracing span, returning Instrumented<Self>.

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.
