Enum SsimError 

pub enum SsimError {
    SizeMismatch {
        img1_width: u32,
        img1_height: u32,
        img2_width: u32,
        img2_height: u32,
    },
    InputTooSmall {
        width: u32,
        height: u32,
        minimum: u32,
    },
    Options(String),
}

Why a metric could not produce a score.

The messages are the ones blazediff’s front-ends have always printed, so a caller wrapping this in its own error type can forward them verbatim.

Variants

SizeMismatch

The two inputs are not the same size.

Fields

img1_width: u32

img1_height: u32

img2_width: u32

img2_height: u32

InputTooSmall

The input is smaller than the chosen metric can work on.

Fields

width: u32

height: u32

minimum: u32

Options(String)

The metric was configured with values it cannot honour.

Trait Implementations

impl Clone for SsimError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SsimError

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

Formats the value using the given formatter.

impl Eq for SsimError

impl Error for SsimError

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 PartialEq for SsimError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
