Struct DiagnosedError 

pub struct DiagnosedError { /* private fields */ }

Internal error wrapper that carries a tip alongside the original error.

This is the actual type inserted into the anyhow chain. The CLI extracts the tip by downcasting to Diagnosed (which this derefs to via the chain’s source).

The Display impl delegates to the source error so the tip doesn’t appear in the error message — only in the rendered output.

Implementations

impl DiagnosedError

pub fn tip(&self) -> &str

Get the remediation tip.

Trait Implementations

impl Debug for DiagnosedError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DiagnosedError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DiagnosedError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
