Enum FromObjectError 

#[non_exhaustive]
pub enum FromObjectError {
    NotAMoveStruct,
    WrongType,
    Bcs(Error),
}

Error returned when converting an Object into a typed mirror.

Every mirror’s TryFrom<&Object> (and try_from_object_with_type) conversion returns this on failure: the object either isn’t a Move struct, carries a type tag that doesn’t match the expected type, or has BCS contents that fail to decode.

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.

NotAMoveStruct

The object is a package, not a Move struct.

WrongType

The Move struct’s type tag does not match the expected type.

Bcs(Error)

BCS decoding of the struct contents failed.

Trait Implementations

impl Debug for FromObjectError

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

Formats the value using the given formatter.

impl Display for FromObjectError

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

Formats the value using the given formatter.

impl Error for FromObjectError

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<Error> for FromObjectError

fn from(source: Error) -> Self

Converts to this type from the input type.
