Enum TryFromError 

pub enum TryFromError {
    UnsupportedSourceShape {
        src_shape: &'static Shape,
        expected: &'static [&'static Shape],
    },
    Generic(String),
}

Error returned when try_from fails to convert a value.

Variants

UnsupportedSourceShape

The source shape is not supported for conversion.

Fields

src_shape: &'static Shape

The shape of the source value.

expected: &'static [&'static Shape]

The expected shapes that would be supported.

Generic(String)

A generic error message.

Trait Implementations

impl Clone for TryFromError

fn clone(&self) -> TryFromError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TryFromError

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

Formats the value using the given formatter.

impl Display for TryFromError

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

Formats the value using the given formatter.

impl Error for TryFromError

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.
