Error type to map a DmaBuf

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.

FdAccess

An Error occurred while accessing the buffer file descriptor

Fields

reason: String

Description of the Error

source: Error

Source of the Error

MappingFailed

An Error occurred while mapping the buffer file descriptor

Fields

reason: String

Description of the Error

source: Error

Source of the Error

IntegerConversionFailed(TryFromIntError)

An Error occurred while converting between Integer types

Trait Implementations

impl Debug for MapError

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

Formats the value using the given formatter.

impl Display for MapError

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

Formats the value using the given formatter.

impl Error for MapError

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 MapError

fn from(source: TryFromIntError) -> Self

Converts to this type from the input type.
