Struct gdbstub::stub::GdbStubError

pub struct GdbStubError<T, C> { /* private fields */ }

An error which may occur during a GDB debugging session.

Additional Notes

GdbStubError’s inherent Display impl typically contains enough context for users to understand why the error occurred.

That said, there are a few instances where the error condition requires additional context.

User error: cannot report stop reason without also implementing its corresponding IDET

This is a not a bug with gdbstub. Rather, this is indicative of a bug in your gdbstub integration.

Certain stop reasons can only be used when their associated protocol feature has been implemented. e.g: a Target cannot return a StopReason::HwBreak if the hardware breakpoints IDET hasn’t been implemented.

Please double-check that you’ve implemented all the necessary supports_ methods related to the stop reason you’re trying to report.

Received an unexpected step request. This is most-likely due to this GDB client bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28440

Unfortunately, there’s nothing gdbstub can do to work around this bug.

Until the issue is fixed upstream, certain architectures are essentially forced to manually implement single-step support.

Implementations

impl<T, C> GdbStubError<T, C>

pub fn is_target_error(&self) -> bool

Check if the error was due to a target error.

pub fn into_target_error(self) -> Option<T>

If the error was due to a target error, return the concrete error type.

pub fn is_connection_error(&self) -> bool

Check if the error was due to a connection error.

pub fn into_connection_error(self) -> Option<(C, ConnectionErrorKind)>

If the error was due to a connection error, return the concrete error type.

Trait Implementations

impl<T: Debug, C: Debug> Debug for GdbStubError<T, C>

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

Formats the value using the given formatter.

impl<T, C> Display for GdbStubError<T, C>

where C: Display, T: Display,

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

Formats the value using the given formatter.

impl<T, C> Error for GdbStubError<T, C>

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

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
