Enum FrameAccessError 

pub enum FrameAccessError {
    NotHostAccessible,
    MaterializationFailed {
        detail: String,
    },
}

Errors from frame data access operations.

Returned by FrameEnvelope::require_host_data() when host bytes cannot be obtained.

Variants

NotHostAccessible

The frame is device-resident with no host materialization path.

MaterializationFailed

A host-materialization path exists but the transfer failed.

Fields

detail: String

Backend-provided failure description.

Trait Implementations

impl Clone for FrameAccessError

fn clone(&self) -> FrameAccessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameAccessError

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

Formats the value using the given formatter.

impl Display for FrameAccessError

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

Formats the value using the given formatter.

impl Error for FrameAccessError

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<FrameAccessError> for ConvertError

fn from(source: FrameAccessError) -> Self

Converts to this type from the input type.
