Enum UpscaleError 

#[non_exhaustive]
pub enum UpscaleError {
    InvalidFactor(u32),
    DimensionOverflow {
        src: (usize, usize),
        factor: u32,
    },
    DimensionMismatch {
        actual: usize,
        expected: usize,
    },
}

Errors returned by upscaling setup or execution.

Variants (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.

InvalidFactor(u32)

The requested factor is not in the supported set {2, 3, 4}.

DimensionOverflow

Upscaled dimensions would overflow usize.

Fields

src: (usize, usize)

factor: u32

DimensionMismatch

The image buffer length does not match the declared src_w * src_h.

Fields

actual: usize

Actual buffer length.

expected: usize

Expected length (src_w * src_h).

Trait Implementations

impl Debug for UpscaleError

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

Formats the value using the given formatter.

impl Display for UpscaleError

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

Formats the value using the given formatter.

impl Error for UpscaleError

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<UpscaleError> for ChessError

fn from(e: UpscaleError) -> Self

Converts to this type from the input type.

impl PartialEq for UpscaleError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
