Struct Diagnosed 

pub struct Diagnosed { /* private fields */ }

Marker type that carries a user-facing tip through the anyhow error chain.

Added automatically by .diagnose() or .with_diagnosis(). The CLI renderer extracts it via a single downcast_ref::<Diagnosed>() — no per-type dispatch needed.

Display returns an empty string so the marker is invisible in the error chain’s “caused by” output.

Implementations

impl Diagnosed

pub fn new(tip: impl Into<String>) -> Self

Create a new diagnosed marker with the given tip.

pub fn tip(&self) -> &str

Get the remediation tip.

Trait Implementations

impl Debug for Diagnosed

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

Formats the value using the given formatter.

impl Display for Diagnosed

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

Formats the value using the given formatter.

impl Error for Diagnosed

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>)
