Implementations

impl Error

pub fn new(kind: ErrorKind) -> Error

Construct a new error given an error kind.

pub fn custom(error: impl CustomError) -> Error

Construct a new, custom error.

pub fn custom_str(error: &'static str) -> Error

Construct a custom error from a static string.

pub fn custom_string(error: String) -> Error

Construct a custom error from an owned string.

pub fn kind(&self) -> &ErrorKind

Retrieve more information about what went wrong.

pub fn context(&self) -> &Context

Retrieve details about where the error occurred.

pub fn at(self, loc: Location) -> Self

Give some context to the error.

pub fn at_idx(self, idx: usize) -> Self

Note which sequence index the error occurred in.

pub fn at_field(self, field: impl Into<Cow<'static, str>>) -> Self

Note which field the error occurred in.

pub fn at_variant(self, variant: impl Into<Cow<'static, str>>) -> Self

Note which variant the error occurred in.

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)>

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<DecodeError> for Error

fn from(err: DecodeError) -> Error

Converts to this type from the input type.
