Invalid register

WriteToReadOnlyRegister

Attempt to write to a read-only register

StopUnwinding

Stop unwinding

InvalidIP

Invalid instruction pointer

BadFrame

Bad frame

BadValue

Unsupported operation or bad value

BadVersion

Unwind info has unsupported version

NoInfo

No unwind info found

Unknown

An error with an unknown error code occured

Fields

code: uw_error_t

The error’s code

Implementations

impl UnwindError

pub const fn from_code(code: uw_error_t) -> Result<uw_error_t, UnwindError>

Creates a Result that is Ok if the error code represents a success and Err if it represents an error.

Trait Implementations

impl Debug for UnwindError

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

Formats the value using the given formatter.

impl Display for UnwindError

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

Formats the value using the given formatter.

impl Error for UnwindError

where Self: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 ErrorCompat for UnwindError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
