Trait SpanExt 

pub trait SpanExt: Sized {
    // Required method
    fn attach_span(self) -> Self;
}

Extension trait for attaching tracing spans to reports.

This trait provides methods to easily attach the current tracing span to a report or to the error contained within a Result.

Examples

Attach tracing span to a report:

use rootcause::report;
use rootcause_tracing::SpanExt;

#[tracing::instrument]
fn example() {
    let report = report!("An error occurred").attach_span();
}

Attach tracing span to a Result:

use rootcause::{Report, report};
use rootcause_tracing::SpanExt;

#[tracing::instrument]
fn might_fail() -> Result<(), Report> {
    Err(report!("operation failed").into_dynamic())
}

let result = might_fail().attach_span();

Required Methods

fn attach_span(self) -> Self

Attaches the current tracing span to the report.

Examples

use rootcause::report;
use rootcause_tracing::SpanExt;

#[tracing::instrument]
fn example() {
    let report = report!("error").attach_span();
}

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
