Enum exif::Error

#[non_exhaustive]
pub enum Error {
    InvalidFormat(&'static str),
    Io(Error),
    NotFound(&'static str),
    BlankValue(&'static str),
    TooBig(&'static str),
    NotSupported(&'static str),
    UnexpectedValue(&'static str),
}

An error returned when parsing of Exif data fails.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidFormat(&'static str)

Input data was malformed or truncated.

Io(Error)

Input data could not be read due to an I/O error and a std::io::Error value is associated with this variant.

NotFound(&'static str)

Exif attribute information was not found in an image file such as JPEG.

BlankValue(&'static str)

The value of the field is blank. Some fields have blank values whose meanings are defined as “unknown”. Such a blank value should be treated the same as the absence of the field.

TooBig(&'static str)

Field values or image data are too big to encode.

NotSupported(&'static str)

The field type is not supported and cannnot be encoded.

UnexpectedValue(&'static str)

The field has an unexpected value.

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 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<&'static str> for Error

fn from(err: &'static str) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.
