Enum exr::error::Error

pub enum Error {
    Aborted,
    NotSupported(Cow<'static, str>),
    Invalid(Cow<'static, str>),
    Io(IoError),
}

An error that may happen while reading or writing an exr file. Distinguishes between three types of errors: unsupported features, invalid data, and file system errors.

Variants

Aborted

Reading or Writing the file has been aborted by the caller. This error will never be triggered by this crate itself, only by users of this library. It exists to be returned from a progress callback.

NotSupported(Cow<'static, str>)

The contents of the file are not supported by this specific implementation of open exr, even though the data may be valid.

Invalid(Cow<'static, str>)

The contents of the image are contradicting or insufficient. Also returned for ErrorKind::UnexpectedEof errors.

Io(IoError)

The underlying byte stream could not be read successfully, probably due to file system related errors.

Implementations

impl Error

pub(crate) fn invalid(message: impl Into<Cow<'static, str>>) -> Self

Create an error of the variant Invalid.

pub(crate) fn unsupported(message: impl Into<Cow<'static, str>>) -> Self

Create an error of the variant NotSupported.

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, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

Returns 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>(&'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

Enable using the ? operator on std::io::Result.

fn from(error: IoError) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for Error

fn from(_: TryFromIntError) -> Self

Converts to this type from the input type.
