Enum TryFromError 

#[non_exhaustive]
pub enum TryFromError {
    Generic(&'static str),
    Unimplemented(&'static Shape),
    Incompatible {
        source: &'static Shape,
        target: &'static Shape,
    },
}

Error type for TryFrom conversion failures

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Generic(&'static str)

Generic conversion error

Unimplemented(&'static Shape)

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

Incompatible

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

Fields

source: &'static Shape

The source shape that we tried to convert from

target: &'static Shape

The target shape that we tried to convert to

Trait Implementations

impl Debug for TryFromError

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

Formats the value using the given formatter.

impl Display for TryFromError

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

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.
