Struct Error

pub struct Error {
    value: String,
    source: Option<Box<dyn Error>>,
}

A simple error implementation which allows chaining of errors, inspired somewhat by anyhow.

Fields

value: String

source: Option<Box<dyn Error>>

Implementations

impl Error

pub fn report(&self) -> ErrorReport<'_>

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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

#[doc(hidden)] fn type_id(&self, _: Internal) -> TypeId

where Self: 'static,

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

Gets the TypeId of self.

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.

impl From<&str> for Error

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Infallible> for Error

fn from(value: Infallible) -> Self

Converts to this type from the input type.

impl From<String> for Error

fn from(value: String) -> Self

Converts to this type from the input type.
