All errors that can occur when attempting to parse a BMP

Variants

CorruptRleData

BitfieldMaskNonContiguous

The bitfield mask interleaves set and unset bits

BitfieldMaskInvalid

Bitfield mask invalid (e.g. too long for specified type)

BitfieldMaskMissing(u32)

Bitfield (of the specified width – 16- or 32-bit) mask not present

BitfieldMasksMissing(u32)

Bitfield (of the specified width – 16- or 32-bit) masks not present

BmpSignatureInvalid

BMP’s “BM” signature wrong or missing

MoreThanOnePlane

More than the exactly one allowed plane specified by the format

InvalidChannelWidth(ChannelWidthError, u16)

Invalid amount of bits per channel for the specified image type

NegativeWidth(i32)

The width is negative

ImageTooLarge(i32, i32)

One of the dimensions is larger than a soft limit

InvalidHeight

The height is i32::min_value()

General negative heights specify top-down DIBs

ImageTypeInvalidForTopDown(u32)

Specified image type is invalid for top-down BMPs (i.e. is compressed)

ImageTypeUnknown(u32)

Image type not currently recognized by the decoder

HeaderTooSmall(u32)

Bitmap header smaller than the core header

PaletteSizeExceeded

The palette is bigger than allowed by the bit count of the BMP

Fields

colors_used: u32

bit_count: u16

Trait Implementations

impl Clone for DecoderError

fn clone(&self) -> DecoderError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DecoderError

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

Formats the value using the given formatter.

impl Display for DecoderError

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

Formats the value using the given formatter.

impl Error for DecoderError

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<DecoderError> for ImageError

fn from(e: DecoderError) -> ImageError

Converts to this type from the input type.

impl Hash for DecoderError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DecoderError

fn cmp(&self, other: &DecoderError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DecoderError

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

impl PartialOrd for DecoderError

fn partial_cmp(&self, other: &DecoderError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
