Enum ExtensionError 

#[non_exhaustive]
pub enum ExtensionError {
    Unsupported(String),
    Malformed(String),
    Budget(String),
    MissingResource(String),
    Mismatch(String),
}

Why a provider could not answer.

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.

Unsupported(String)

No registered provider reads these bytes, or the provider asked for is not in this build.

Malformed(String)

The bytes are not a well-formed file of the format.

Budget(String)

The file is larger than a provider opens.

MissingResource(String)

A resource the source needs is not registered.

Mismatch(String)

The media is not what the project says it is.

Trait Implementations

impl Eq for ExtensionError

impl Error for ExtensionError

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 ExtensionError

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

Equality operator ==.

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

Inequality operator !=.
