Enum zng_app::view_process::EncodeError

pub enum EncodeError {
    Encode(Txt),
    Dummy,
    ViewProcessOffline,
}

Error returned by ViewImage::encode.

Variants

Encode(Txt)

Encode error.

Dummy

Attempted to encode dummy image.

In a headless-app without renderer all images are dummy because there is no view-process backend running.

ViewProcessOffline

The View-Process disconnected or has not finished initializing yet, try again after VIEW_PROCESS_INITED_EVENT.

Trait Implementations

impl Clone for EncodeError

fn clone(&self) -> EncodeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EncodeError

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

Formats the value using the given formatter.

impl Display for EncodeError

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

Formats the value using the given formatter.

impl Error for EncodeError

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<RecvError> for EncodeError

fn from(_: RecvError) -> Self

Converts to this type from the input type.

impl From<Txt> for EncodeError

fn from(e: Txt) -> Self

Converts to this type from the input type.

impl From<ViewProcessOffline> for EncodeError

fn from(_: ViewProcessOffline) -> Self

Converts to this type from the input type.

impl PartialEq for EncodeError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
