Struct ErrorString

pub struct ErrorString(/* private fields */);

A wrapper struct for an error string. This can be used when no complex error variant is needed.

Trait Implementations

impl Clone for ErrorString

fn clone(&self) -> ErrorString

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorString

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

Formats the value using the given formatter.

impl Display for ErrorString

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

Formats the value using the given formatter.

impl Error for ErrorString

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.

impl From<&str> for ErrorString

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<ErrorString> for ExtensionError

fn from(source: ErrorString) -> Self

Converts to this type from the input type.

impl From<String> for ErrorString

fn from(s: String) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorString

fn eq(&self, other: &ErrorString) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
