Struct Error

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

Single error when of parsing configuration file

Usually you use ErrorList which embeds multiple errors encountered during configuration file parsing

Implementations

impl Error

pub fn open_error(path: &Path, err: Error) -> Error

pub fn parse_error(pos: &Pos, message: String) -> Error

pub fn tokenizer_error((pos, err): (Pos, Error)) -> Error

pub fn validation_error(pos: &Pos, message: String) -> Error

pub fn decode_error(pos: &Pos, path: &String, message: String) -> Error

pub fn preprocess_error(pos: &Pos, message: String) -> Error

pub fn custom<T: StdError + Send + Sync + 'static>(err: T) -> Error

pub fn custom_at<T: StdError + Send + Sync + 'static>( pos: &Pos, err: T, ) -> Error

pub fn downcast_ref<T: StdError + 'static>(&self) -> Option<&T>

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 cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

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 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 Error for Error

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.
