Trait Implementations

impl<T: Clone, Nt: Clone, E: Clone> Clone for ViewConstructionError<T, Nt, E>

fn clone(&self) -> ViewConstructionError<T, Nt, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, Nt: Debug, E: Debug> Debug for ViewConstructionError<T, Nt, E>

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

Formats the value using the given formatter.

impl<T, Nt, E> Display for ViewConstructionError<T, Nt, E>

where CstNodeData<T, Nt>: Debug, NodeKind<T, Nt>: Debug, E: Display,

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

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<T, Nt, E> From<E> for ViewConstructionError<T, Nt, E>

fn from(source: E) -> Self

Converts to this type from the input type.
