Enum TryFromError

pub enum TryFromError<'shape> {
    Generic(&'static str),
    Unimplemented,
    UnsupportedSourceShape {
        src_shape: &'shape Shape<'shape>,
        expected: &'shape [&'shape Shape<'shape>],
    },
    Unsized,
}

Error type for TryFrom conversion failures

Variants

Generic(&'static str)

Generic conversion error

Unimplemented

The target shape doesn’t implement conversion from any source shape (no try_from in vtable)

UnsupportedSourceShape

The target shape has a conversion implementation, but it doesn’t support converting from this specific source shape

Fields

src_shape: &'shape Shape<'shape>

The source shape that failed to convert

expected: &'shape [&'shape Shape<'shape>]

The shapes that the TryFrom implementation supports

Unsized

!Sized type

Trait Implementations

impl<'shape> Clone for TryFromError<'shape>

fn clone(&self) -> TryFromError<'shape>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'shape> Debug for TryFromError<'shape>

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

Formats the value using the given formatter.

impl<'shape> Display for TryFromError<'shape>

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

Formats the value using the given formatter.

impl<'shape> Error for TryFromError<'shape>

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<'shape> From<UnsizedError> for TryFromError<'shape>

fn from(_value: UnsizedError) -> Self

Converts to this type from the input type.

impl<'shape> PartialEq for TryFromError<'shape>

fn eq(&self, other: &TryFromError<'shape>) -> bool

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

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

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