Trait WithCollector

pub trait WithCollector: Sized {
    // Provided methods
    fn with_collector<C>(self, collector: C) -> WithDispatch<Self> 
       where C: Into<Dispatch> { ... }
    fn with_current_collector(self) -> WithDispatch<Self>  { ... }
}

Available on crate feature std only.

Extension trait allowing futures, streams, and sinks to be instrumented with a tracing collector.

Provided Methods

fn with_collector<C>(self, collector: C) -> WithDispatch<Self>

where C: Into<Dispatch>,

Attaches the provided collector to this type, returning a WithDispatch wrapper.

When the wrapped type is a future, stream, or sink, the attached subscriber will be set as the default while it is being polled. When the wrapped type is an executor, the subscriber will be set as the default for any futures spawned on that executor.

fn with_current_collector(self) -> WithDispatch<Self>

Attaches the current default collector to this type, returning a WithDispatch wrapper.

When the wrapped type is a future, stream, or sink, the attached subscriber will be set as the default while it is being polled. When the wrapped type is an executor, the subscriber will be set as the default for any futures spawned on that executor.

This can be used to propagate the current dispatcher context when spawning a new future.

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.
