Enum RasterError 

#[non_exhaustive]
pub enum RasterError {
    InvalidDpi,
    EmptyPageSelection,
    PageOutOfRange {
        page_index: usize,
        page_count: usize,
    },
    DuplicatePage {
        page_index: usize,
    },
    InvalidJpegQuality {
        quality: u8,

    },
}

A reason a raster export request could not be completed.

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.

InvalidDpi

DPI was NaN, infinite, zero, or negative.

EmptyPageSelection

No page was selected.

PageOutOfRange

A selected zero-based page index does not exist.

Fields

page_index: usize

page_count: usize

DuplicatePage

A selected zero-based page index appears more than once.

Fields

page_index: usize

InvalidJpegQuality

JPEG quality must be in the inclusive 1 through 100 range.

Fields

quality: u8

InvalidDimensions

The requested raster dimensions cannot be represented.

EncodeFailed

The rendered pixmap could not be encoded into the requested format.

Fields

format: &'static str

Trait Implementations

impl Clone for RasterError

fn clone(&self) -> RasterError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RasterError

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

Formats the value using the given formatter.

impl Display for RasterError

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

Formats the value using the given formatter.

impl Eq for RasterError

impl Error for RasterError

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 RasterError

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

Equality operator ==.

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

Inequality operator !=.
