Enum ocrs::ImageSourceError

pub enum ImageSourceError {
    UnsupportedChannelCount,
    InvalidDataLength,
}

Errors that can occur when creating an ImageSource.

Variants

UnsupportedChannelCount

The image channel count is not 1 (greyscale), 3 (RGB) or 4 (RGBA).

InvalidDataLength

The image data length is not a multiple of the channel size.

Trait Implementations

impl Clone for ImageSourceError

fn clone(&self) -> ImageSourceError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageSourceError

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

Formats the value using the given formatter.

impl Display for ImageSourceError

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

Formats the value using the given formatter.

impl Error for ImageSourceError

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>(&'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 PartialEq for ImageSourceError

fn eq(&self, other: &ImageSourceError) -> 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.
