Enum DecodeError 

#[non_exhaustive]
pub enum DecodeError {
    Unrecognised,
    Disabled(&'static str),
    Malformed(String),
    TooLarge {
        width: u32,
        height: u32,
    },
    Unsupported(&'static str),
}

Why a decode failed.

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.

Unrecognised

The bytes match no format this crate knows.

Disabled(&'static str)

The format was recognised, but its decoder is compiled out — the named cargo feature would enable it.

Malformed(String)

The file is damaged, truncated, or not what its header claims. The message is the underlying decoder’s.

TooLarge

The header asks for more than MAX_PIXELS pixels. Reported before anything is allocated.

Fields

width: u32

Claimed width in pixels.

height: u32

Claimed height in pixels.

Unsupported(&'static str)

A valid file in a variant this crate does not support, such as a compressed or 16-colour BMP.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

impl Error for DecodeError

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 DecodeError

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

Equality operator ==.

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

Inequality operator !=.
