Trait Implementations

impl Debug for DocumentError

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

Formats the value using the given formatter.

impl Display for DocumentError

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

Formats the value using the given formatter.

impl Eq for DocumentError

impl Error for DocumentError

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<CanvasSchemaError> for DocumentError

fn from(source: CanvasSchemaError) -> Self

Converts to this type from the input type.

impl From<DocumentError> for JsonCanvasError

fn from(source: DocumentError) -> Self

Converts to this type from the input type.

impl<E> From<DocumentError> for CanvasPersistenceError<E>

fn from(value: DocumentError) -> Self

Converts to this type from the input type.

impl From<DocumentError> for CanvasToolRegistryError

fn from(value: DocumentError) -> Self

Converts to this type from the input type.

impl PartialEq for DocumentError

fn eq(&self, other: &DocumentError) -> 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.
