Struct Bug 

pub struct Bug {
    pub operation: &'static str,
    pub message: String,
    pub location: Option<SourceLocation>,
    pub kind: BugKind,
}

Work that panicked: a bug in it, not a failure its caller can act on (E15). The caller reports it wherever it reports its own bugs, and the call that ran the work returns it as its error.

Fields

operation: &'static str

What the work was doing, as its caller named it.

message: String

The text the panic carried (panic_message).

location: Option<SourceLocation>

Where the bug showed itself: where the panic began, or where the code that found the bug made it (Bug::new). None for a panic no catch of coven’s saw begin: one that reached a join uncaught (TaskFailed::of_join), or one resumed with std::panic::resume_unwind from a panic elsewhere.

kind: BugKind

Whether the bug showed itself as a panic or code found it.

Implementations

impl Bug

pub fn new(operation: &'static str, message: impl Into<String>) -> Self

The bug code found in operation without a panic, such as state a Drop finds wrong, located where this is called.

Trait Implementations

impl CarriesBug for Bug

fn bug(&self) -> Option<&Bug>

The bug this error carries, itself or through the failure it keeps.

impl Clone for Bug

fn clone(&self) -> Bug

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bug

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

Formats the value using the given formatter.

impl Display for Bug

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

Formats the value using the given formatter.

impl Error for Bug

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<Bug> for BootstrapDirectoryError

fn from(source: Bug) -> Self

Converts to this type from the input type.

impl From<Bug> for CopyPathError

fn from(source: Bug) -> Self

Converts to this type from the input type.

impl From<Bug> for FileError

fn from(source: Bug) -> Self

Converts to this type from the input type.

impl From<Bug> for SettingsError

fn from(source: Bug) -> Self

Converts to this type from the input type.

impl From<Bug> for StoreLockError

fn from(source: Bug) -> Self

Converts to this type from the input type.

impl PartialEq for Bug

fn eq(&self, other: &Bug) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
