Struct AnnotatedMessage 

pub struct AnnotatedMessage { /* private fields */ }

A simple annotated message that can be attached to errors using the anyhow::Context methods, or be used as an error type itself. The recommended way to use this for error context is using atry! or related macros.

The std::fmt::Display of this type yields its primary “message”. Consumers that are aware of this type can obtain additional context through its notes() method.

Implementations

impl AnnotatedMessage

pub fn set_message<T: Display>(&mut self, m: T)

Set the primary message associated with this annotated report.

pub fn add_note<T: Display>(&mut self, n: T)

Add an additional note to be associated with this annotated report.

pub fn notes(&self) -> &[String]

Obtain the set of notes associated with this report.

Trait Implementations

impl Debug for AnnotatedMessage

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

Formats the value using the given formatter.

impl Default for AnnotatedMessage

fn default() -> AnnotatedMessage

Returns the “default value” for a type.

impl Display for AnnotatedMessage

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

Formats the value using the given formatter.

impl Error for AnnotatedMessage

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
