Struct sval::Error

pub struct Error(_);

An error encountered while visiting a value.

Converting an Error into a standard error

The Error type doesn't implement the std::error::Error trait directly. When std is available, the into_error method will convert an Error into a value that implements std::error::Error.

Implementations

impl Error

pub fn custom(err: impl Display) -> Self

Get an error from a format.

impl Error

pub fn into_io_error(self) -> Error

Convert into an io error.

impl Error

pub fn msg(msg: &'static str) -> Self

Capture a static message as an error.

pub fn unsupported(operation: &'static str) -> Self

Declare some structure as unsupported.

pub fn is_unsupported(&self) -> bool

Whether or not an error is because some operation was unsupported.

pub fn into_fmt_error(self) -> Error

Convert into a fmt::Error

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.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

fn from(_: Error) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(err: Error) -> Self

Performs the conversion.
