Implementations

impl Error

pub fn invalid_value<T>(expected: T) -> Error

where T: ToString,

Create an invalid value error with a given expected type name.

pub const fn invalid_value_static(expected: &'static str) -> Error

Create an invalid value error with a given expected type name.

pub fn custom<T>(msg: T) -> Error

where T: ToString,

Create a custom error with a given error message.

pub const fn custom_static(msg: &'static str) -> Error

Create a custom error with a given error message.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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.

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<ErrorList<NamedFieldError>> for Error

fn from(errors: ErrorList<NamedFieldError>) -> Error

Converts to this type from the input type.

impl From<ErrorList<UnnamedFieldError>> for Error

fn from(errors: ErrorList<UnnamedFieldError>) -> Error

Converts to this type from the input type.

impl From<NamedFieldError> for Error

fn from(err: NamedFieldError) -> Error

Converts to this type from the input type.

impl From<UnnamedFieldError> for Error

fn from(err: UnnamedFieldError) -> Error

Converts to this type from the input type.
