Struct lldb::SBError

pub struct SBError {
    pub raw: SBErrorRef,
}

A container for holding any error code and an error message.

An SBError is used to indicate whether or not an operation has succeeded or failed, along with an indication of why it has failed.

To check if the operation has succeeded, use SBError::is_success(). If it has failed, then SBError::is_failure() will return true, and more information about the error can be obtained from SBError::error(), SBError::error_string(), and SBError::error_type().

Fields

raw: SBErrorRef

The underlying raw SBErrorRef.

Implementations

impl SBError

pub fn maybe_wrap(raw: SBErrorRef) -> Option<SBError>

Construct a new Some(SBError) or None.

pub fn is_success(&self) -> bool

Does this error represent a success?

An error starts out in the success state by default:

let e = SBError::default();
assert!(e.is_success());

• SBError::into_result()
• SBError::is_failure()

pub fn is_failure(&self) -> bool

Does this error represent a failure?

See also:

• SBError::error()
• SBError::error_string()
• SBError::error_type()
• SBError::into_result()
• SBError::is_success()

pub fn into_result(self) -> Result<(), SBError>

Convert to a Result<(), SBError>.

An SBError represents either a success or a failure. This method converts the success variant to Ok(()) and the error variant to Err(self).

let e = SBError::default();
// Do something with `e`.
let r = e.into_result();

• SBError::error_string()
• SBError::error_type()

pub fn error(&self) -> u32

The underlying error code. Must be interpreted in conjunction with the error type.

See also:

• SBError::error_string()
• SBError::error_type()

pub fn error_string(&self) -> &str

Any textual error message associated with the error.

See also:

• SBError::error()
• SBError::error_type()

pub fn error_type(&self) -> ErrorType

What type of error is this?
