Enum Error

pub enum Error {
    InvalidFormat(Cow<'static, str>),
    UnexpectedEndOfFile(Option<Cow<'static, str>>),
    Io(Error),
}

Library-specific error type which is returned by metadata loading operations.

Variants

InvalidFormat(Cow<'static, str>)

Returned when metadata can’t be recovered because image format is invalid.

This error can be caused by broken file or when trying to load an image with an incorrect metadata decoder, e.g. trying to load PNG metadata from JPEG.

UnexpectedEndOfFile(Option<Cow<'static, str>>)

Returned when metadata can’t be recovered because of the sudden end of the image file.

Usually this error is caused by broken files, but it may also be cause by applying loose formats (like JPEG) to a different image type.

Io(Error)

Returned when an I/O error occurs when reading an input stream.

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 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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(e: Error) -> Error

Converts to this type from the input type.
