Enum rexiv2::Rexiv2Error

pub enum Rexiv2Error {
    NoValue,
    Utf8(Utf8Error),
    Internal(Option<String>),
}

A wrapper type for the kinds of errors one might encounter when using the library.

Variants

Utf8(Utf8Error)

See std::str::Utf8Error

Internal(Option<String>)

An error generated from the wrapped gexiv2 or Exiv2 libraries.

May or may not contain a description message.

Trait Implementations

impl Debug for Rexiv2Error

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

Formats the value using the given formatter.

impl Display for Rexiv2Error

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

Formats the value using the given formatter.

impl Error for Rexiv2Error

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)>

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 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<Utf8Error> for Rexiv2Error

fn from(err: Utf8Error) -> Rexiv2Error

Converts to this type from the input type.

impl PartialEq<Rexiv2Error> for Rexiv2Error

fn eq(&self, other: &Rexiv2Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
