Implementations

impl NamedFieldError

pub fn new<T>(field: T, error: Error) -> NamedFieldError

where T: ToString,

Create a new error for a given named field.

pub const fn new_static(field: &'static str, error: Error) -> NamedFieldError

Create a new error for a given named field.

pub fn field(&self) -> &str

Get the name of the field.

pub fn error(&self) -> &Error

Trait Implementations

impl Clone for NamedFieldError

fn clone(&self) -> NamedFieldError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NamedFieldError

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

Formats the value using the given formatter.

impl Display for NamedFieldError

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

Formats the value using the given formatter.

impl Error for NamedFieldError

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<NamedFieldError> for Error

fn from(err: NamedFieldError) -> Error

Converts to this type from the input type.
