Struct anomaly::Context

pub struct Context<Kind> where
    Kind: Clone + Debug + Display + Into<BoxError>,  { /* private fields */ }

Error context: stores an error source (as a BoxError) and backtrace along with an error Kind.

Implementations

impl<Kind> Context<Kind> where
    Kind: Clone + Debug + Display + Into<BoxError>, 

pub fn new(kind: Kind, source: Option<BoxError>) -> Self

Create a new error context

pub fn kind(&self) -> &Kind

Get the kind of error

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

Get the backtrace associated with this error (if available)

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
