pub enum Error {
    CannotResolve {
        iova_range: IovaRange,
        reason: String,
    },
    Fragmented {
        iova_range: IovaRange,
        continuous_length: usize,

}

Available on crate feature iommu only.

Errors associated with IOMMU address translation.

Variants

CannotResolve

Lookup cannot be resolved.

Fields

iova_range: IovaRange

IOVA range that could not be resolved

reason: String

Some human-readable specifics about the reason

Fragmented

Wanted to translate an IOVA range into a single slice, but the range is fragmented.

Fields

iova_range: IovaRange

Full IOVA range that was to be translated

continuous_length: usize

Length of the continuous head (i.e. the first fragment)

IommuMisconfigured

IOMMU is not configured correctly, and so cannot translate addresses.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
