Trait Implementations

impl AnyCompatible for Error

fn type_str() -> String

the type string of the type

unsafe fn copy_to_any_view(src: &Self, data: &mut TVMFFIAny)

the value to copy to TVMFFIAny

unsafe fn check_any_strict(data: &TVMFFIAny) -> bool

unsafe fn copy_from_any_view_after_check(data: &TVMFFIAny) -> Self

Copy value from TVMFFIAny after checking caller must ensure that the value is compatible with the type

unsafe fn move_to_any(src: Self, data: &mut TVMFFIAny)

consume the value to move to Any

unsafe fn move_from_any_after_check(data: &mut TVMFFIAny) -> Self

the value to move from TVMFFIAny NOTE: pay very careful attention to avoid memory leak!

unsafe fn try_cast_from_any_view(data: &TVMFFIAny) -> Result<Self, ()>

try to cast the value from AnyView

fn get_mismatch_type_info(data: &TVMFFIAny) -> String

Get the type key of a type when TryCastFromAnyView fails.

impl<'a> ArgIntoRef for &'a Error

type Target = Error

fn to_ref(&self) -> &Self::Target

impl ArgIntoRef for Error

type Target = Error

fn to_ref(&self) -> &Self::Target

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
