Struct ErrorContext

pub struct ErrorContext {
    pub context: SharedString,
    pub cause: Option<Arc<dyn Error + Send + Sync + 'static>>,
}

An annotated error stack

Fields

context: SharedString

cause: Option<Arc<dyn Error + Send + Sync + 'static>>

Implementations

impl ErrorContext

pub fn new<T>(msg: T) -> ErrorContext

where T: Into<SharedString>,

Trait Implementations

impl Clone for ErrorContext

fn clone(&self) -> ErrorContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorContext

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

Formats the value using the given formatter.

impl Display for ErrorContext

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

Formats the value using the given formatter.

impl Error for ErrorContext

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<Error> for ErrorContext

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorContext

ErrorContext values are compared using pointer equality.

In practice this means that two instances of the same error generated by separate function calls will not be equal, but two clones of the same error will be equal.

Errors without a cause, created using &'static str are an exception to this.

fn eq(&self, other: &Self) -> 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.
