Enum ZoomFitError 

pub enum ZoomFitError {
    RegionSizeXZero,
    RegionSizeYZero,
    OutputSizeXZero,
    OutputSizeYZero,
    LogarithmConversionError(TryFromIntError),
    ZoomLevelError(ZoomLevelError),
}

Errors that can occur when trying to find the correct zoom level to fit regions into an output image of a given size

Variants

RegionSizeXZero

The region size in the x direction can not be zero

RegionSizeYZero

The region size in the y direction can not be zero

OutputSizeXZero

The output image size in the x direction can not be zero

OutputSizeYZero

The output image size in the y direction can not be zero

LogarithmConversionError(TryFromIntError)

Error converting a logarithm value into a u8 (should never happen)

ZoomLevelError(ZoomLevelError)

Error creating the zoom level from the calculated value (should never happen)

Implementations

pub const fn is_region_size_y_zero(&self) -> bool

Returns true if the enum is ZoomFitError::RegionSizeYZero otherwise false

pub const fn is_output_size_x_zero(&self) -> bool

Returns true if the enum is ZoomFitError::OutputSizeXZero otherwise false

pub const fn is_output_size_y_zero(&self) -> bool

Returns true if the enum is ZoomFitError::OutputSizeYZero otherwise false

pub const fn is_logarithm_conversion_error(&self) -> bool

Returns true if the enum is ZoomFitError::LogarithmConversionError otherwise false

pub const fn is_zoom_level_error(&self) -> bool

Returns true if the enum is ZoomFitError::ZoomLevelError otherwise false

Trait Implementations

impl Clone for ZoomFitError

fn clone(&self) -> ZoomFitError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZoomFitError

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

Formats the value using the given formatter.

impl Display for ZoomFitError

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

Formats the value using the given formatter.

impl Error for ZoomFitError

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<TryFromIntError> for ZoomFitError

fn from(source: TryFromIntError) -> Self

Converts to this type from the input type.

impl From<ZoomLevelError> for ZoomFitError

fn from(source: ZoomLevelError) -> Self
