Struct ErrorStackHandler 

pub struct ErrorStackHandler<C>(/* private fields */);

Available on crate feature compat-error-stack05 only.

A custom handler for error_stack::Report that delegates to error-stack’s own formatting.

This handler ensures that error_stack::Report objects display identically whether they’re used directly or wrapped in a rootcause Report. You typically don’t need to use this handler directly - it’s used automatically by the IntoRootcause trait.

Implementation Details

• Display: Uses error_stack::Report’s Display implementation
• Debug: Uses error_stack::Report’s Debug implementation
• Source: Uses the current context’s source method to traverse the error chain
• Formatting style: Matches the report’s formatting function (Display or Debug)

Examples

use rootcause::{Report, compat::error_stack05::ErrorStackHandler};

let es_report = error_stack::Report::new(std::io::Error::from(std::io::ErrorKind::NotFound));
let report: Report<_> = Report::new_custom::<ErrorStackHandler<_>>(es_report);

Type Parameters

• C: The context type of the error-stack report, which must implement Error + Send + Sync + 'static
