Enum exif::Error

source ·
#[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), }
Expand description

An error returned when parsing of Exif data fails.

Variants (Non-exhaustive)§

This enum is marked as 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.
