A preview-generation operation failed for a structural reason (e.g. zero rows/cols, or an internal filter-graph/encode step failed).

Fields

reason: String

Human-readable description of the failure.

Ffmpeg

An underlying FFmpeg function returned an error code.

Fields

Trait Implementations

impl Debug for PreviewImageError

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

Formats the value using the given formatter.

impl Display for PreviewImageError

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

Formats the value using the given formatter.

impl Error for PreviewImageError

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<Error> for PreviewImageError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl MediaError for PreviewImageError

fn severity(&self) -> ErrorSeverity

Classifies this error.

fn is_recoverable(&self) -> bool

Returns true if the failing operation can be retried without rebuilding.

fn is_fatal(&self) -> bool

Returns true if the component must be discarded or reconfigured.
